Heat Me With Your Best Pot... Fryer Away!
Heat Me With Your Best Pot... Fryer Away!
This post is also going to be lengthy. But that’s because it needs to be. I equate it to this… All the time in the kitchen I would have some young little hot shot right out of school come up to me all smirk and smug and say “hey, uh.. you know there’s a quicker way to do that, Chef”. To which my reply, like a broken record, was always, “Do you know why I’m doing it this way? “ and he/she would always say "No", and then I would say, "how the hell are you going to know the quick way if you don’t know the classic way, or even understand the principals and concepts. Go home tonight and read everything you can find about what I’m doing, and why I’m doing it the way I’m doing it. Then, stay after work tomorrow night, I’ll buy you a beer or two and we’ll round-table this for 45 mins – hour. Because I want you to be informed... It's only gong to help you out further down the road in your career." No one did this for me. I was on my own. I was told what to do, and if I didn't know how to do it, I'd better fake the hell out of it until my shift was over - because in the kinds of kitchens I came up, you DIDN'T ask questions. You were told what to do and you were expected to know how to do it... flawless execution of spontaneous tasks delegated to you by your superiors separated the men from the boys. You learn this quick... Especially when you have 20 people behind you ready to snipe with all guns blazing to take your job if you show even 1 iota of weakness. I'd go home often and research all corners of the interwebs and immerse myself in all of the info I could so I could go in the next day looking like I'd been doing "it" for years. Lots of sleepless nights as a young cook. Lots of unpaid work hours, just so I could be there in
wee hours of the morning and stay until well after the last person in the kitchen left so I could just... LEARN. That's how you get ahead. In your 20's you're there to learn... Not to be Executive Chef at 22. It took me a long time to realize that.
Right about now you're probably thinking to yourself... I've read an entire page of marshmallow fluff, but he hasn't even told us what he's pontificating about this week?
Do you know how to keep a blonde in suspense? I'll tell you tomorrow.
This week we're going to talk about HEAT. All about heat. How heat alters food. Caramelization and the Maillard Reaction, Cooking Techniques and how they work, and what's best for what. This is a "warm-up" to a long series of weekly posts that are going to span 2/3rd's of the year if I do it right. We're going to start with heat, because, well, without it, I wouldn't be typing this. Not electricity, but heat. FIRE! For without fire, there would be no cooking. There would be lots of salads and ceviches, but no cooking. <-- (For anyone that doesn't know this, Ceviche isn't cooked, it only appears cooked. But anyway different post. Maybe around mid-July. ) Fire is the basic elemental ingredient that changed how we ate (and were able to digest food) starting around 1 million years ago - some researches say up to 1.8 million years ago, but further evidence is still being analyzed to push the date back that far. For more on that, check out the Wonderwerk Cave in South Africa (Wikipedia). Anyway, we can't talk about anything else without first talking about heat; and how everything from this point forward is going to stand on each other's shoulders. From heat we're going to go into the 5 senses and talk about how we use and apply them harmoniously with heat to cook food and know when it is "done" (which is a relative term very open to interpretation that varies from person to person). After that we're going to go on an exploration of tastes. But not the just four your thinking (hot, sour, salty, sweet), some say there's upwards of 60 - all the way up to 100! But we're only going to look at about 20 of them... and again, how they relate to cooking/eating, and how we use them in conjunction and contrast to each other to make the perfect food. So, as we keep going, each post is going to be a matryoshka doll of the next until we talk this down to the very last grain of salt. And anyone who makes it all the way to the end, the good news is there'll be a closed book test, on a Saturday morning. Just kidding!!! TALLYHO!!!
Fire Good. Fire Cook! - How Cooking Alters Food –
What Is Cooking???
Cooking is the use of heat to produce a safe, edible, tasteful, and digestible product. There are many factors in cooking that change the composition of ingredients. The application of heat affects the texture, nutrition, color, aroma, flavor, and changes protein structure. The amount of change is varied by technique, temperature, and time.
- Texture – the texture of food changes during cooking because of the moisture that is lost. Proteins coagulate and tissues soften. Water molecules in food turn into steam when goes into the air and the fibers become more soluble – altering the texture of what is being cooked.
- Nutrition – All food will start to break down and lose their nutrient value when heat is applied. The amount of nutrient loss is varied by technique, temperature and time. Steaming is the most effective way to blanche vegetables – least amount of damage to the vegetable and they retain nutrients that are not lost in a poaching medium.
- Color – As heat is applied to food, the chemical composition changes, which in turn makes the appearance change. Sugars in food react with heat in what is know as the Maillard Reaction, also referred to as caramelizing. Typically, the longer a food cooks, the more the color will change, usually darken.
- Aroma – While food cooks – especially when cooked over direct heat, the aroma will change.
- Flavor – Using different cooking techniques, combined with ingredients cooked at different stages in their cooking process will result in different flavors and can drastically change the final taste of a composed plate or dish. Take some time and learn how to use different ingredients in stages of a multi-layered cooking process to achieve different and more complex results.
- The Coagulation of Proteins – When food cooks, the proteins inside coagulate, or change from a liquid to solid state. The longer proteins cook, the more firm they become. Because moisture is lost during the coagulation process, proteins will shrink. Following coagulation, proteins will naturally start to break down the collagen and the elastin in meat. Long cooking techniques (braising and stewing) are a great example of this.
In 1912, a French chemist named Louis Camille Maillard discovered that there was a reaction between amino acids and sugars in proteins when applied to heat (over 300 degrees - more on that in a minute) that resulted in new flavors and aromas in browned food to develop. As Maillard discovered this reaction, it rightfully bears his name. Lets talk a little more about the Maillard Reaction.
The Maillard Reaction is a reaction that takes place generally under dry heat cooking process conditions and occurs when heat is applied to a protein, causing the tissues to soften and allow for reducing sugars to be released from the DNA and amino acids to be released from the protein. When these two molecules come into contact with each other, they react and form new and more complex chemical flavor compounds and the simple sugars (ribose and glucose are examples of simple sugars in many proteins) breakdown and then something amazing happens. During this reaction process, new bonds are created between the sugars and the amino acids that link together in ring-like structures and reflect light in a way that makes food take on that signature "browned" color and crust. Now back to the temperature thing. In order for this reaction to occur, not only is heat needed, but the temperature of the heat needs to be above 300 degrees... at a minimum. Up around the 320-330 degrees mark is when we starting seeing more noticeable browning. Above the 330 degrees temperature we start seeing rapid breakdown of the sugars, and then when the temperatures exceed 400 degrees, pyrolysis will eventually occur (your food starts to burn). Let's break all of that down a little bit.
- 300-320:330 - noticeable/visual and olfactory reaction occurring
- 330-350 - the "sweet-spot". This is where you are going to get the most even reaction across the surface of the protein.
- 350-400 - The reaction is happening faster and flavors are getting more complex. The flavors developed in this temperature range are going to be more roasty, malted, and are going to be approaching bitter if not careful.
- 400+ You're playing with fire here... No pun intended. Deep, dark flavors and aromas are produced at these temperatures. At this temperature there is more margin for error as the browning may be very uneven with some spots maturing to burnt before other spots have even picked up color. I'm not saying this temperature is off-limits, but does require a bit more attention and skill to ensure even browning and not burning. Also, of note, pyrolysis has been said to be carcinogenic. But remember back in like 2007 there was a smear campaign (by who I don't know) against grilled food, saying the "charring" from the grates of the grill was said to be linked to carcinogenic cancer causing cells. Well, same thing. Same exact thing. But some of us love "bitter". Along with sour and salty, bitter completes my favorite flavors pyramid.
But that's not it.. we're only like halfway into the Maillard Reaction. I keep bringing up dry heat. As I'll further breakdown dry heat cooking process below, dry heat is needed for the Maillard Reaction to take place. This goes back to the temperature... For Maillard to work the temperature needs to be above 300 degrees - and no moisture, obviously. Water, at sea level, boils at 212 degrees, here 198 degrees. Not hot enough for this reaction to occur. Also, excess water and/or moisture will not allow for reaction to happen, again, because of temperature. So if you have ever seen a recipe that tells you to make sure the surface of your protein is patted dry before cooking, this is why. To take it a step further, if you have ever seen a recipe for your Thanksgiving turkey to be left for 24 hours in the refrigerator uncovered before cooking, this is why - so the exterior can dry out and take on the best crust and color that it can during the cooking process.
Now, Caramelization. Caramelization is the breakdown and reaction of sugars from heat. The difference between caramelization and Maillard is that protein needs to be present. If protein is not present the reaction is caramelization - where the present sugars are undergoing thermal decomposition due to the high heat. To sum this up a bit more clearly, fruits and vegetables caramelize because of the lack of the presence of protein (or they appear in such small amounts their impact is nill. So, as the Maillard Reaction leads to browning and Caramelization is only the breakdown of sugar, can we by definition, use the two words interchangeable? NO! Doing that would be a bigger social faux pas than the time in 2010 when David Cameron showed up in China to observe Remembrance Day wearing a red poppy lapel. (I didn't forget.)
That about wraps up the Maillard Reaction and Caramelization in a nutshell. Except for this one last thing... and this is HUGE! If I have ever taken a utensil out of your hands because you're constantly stirring, poking or prodding, this is for you. The Maillard Reaction and Caramelization are chemical reactions that occur, again, when the temperature is right. When you remove the contact from the temperature required, the process stops, only to start again when contact has been re-established and the temperature rises to where it needs to be for the desired reaction to take place. This leads to uneven browning or caramelization!!! Let your food cook - it's chilling out and doing its thing. I know you think it's sticking, and that's because it is. Your food will tell you when its ready to be turned. It will release when that crust has formed/sugars have caramelized... I promise you. And you're flavor will be better by leaps and bounds.! Now lets move on to how heat mixed with cooking process makes this all possible.
How the Transfer of Heat Works –
Cooking is using heat to alter food. There are four ways that heat can be transferred:
- Conduction – The direct physical contact between two items, where heat moves inward throughout the food.
- Induction – A quicker cooking method using magnetic electricity transfer to heat cookware using a circular magnetic current to conduct heat. Aluminum and copper cannot be used because they have no magnetic properties. This is another example of heat being transferred to food through conduction.
- Convection – Heat being distributed by a liquid medium, or air. There are 2 types of convection: natural & mechanical. Natural Convection uses the natural transfer of heat from top to bottom in a circular motion. The liquid at the bottom of the vessel is heated and rises and the cooler liquid at the top falls to the bottom to reheat. Mechanical Convection is an outside convection source such as a fan blowing oven. Fans used in cooking devices heat quicker and circulate air quicker. This helps for an enhanced distribution of heat.
- Radiation (Infrared & Microwave) – this is the transfer of energy through waves. Waves convert into heat when they come in contact with food. Infrared cooking is when elements heat up to a very high temperature and distribute their heat waves. The waves travel at the speed of light in every direction and the food absorbs them. Microwave Radiation is a special piece of equipment that generates invisible waves and cooks the food by exciting the molecules inside the food which creates friction and heat spreads, cooking the food from the inside out.
Cooking Methods –
The transfer of heat can occur in many different forms, producing different results. Cooking methods are further sub classified by the type of heat applied. There are 3 ways you can apply heat.
- Dry Cooking – a dry cooking technique that transfers heat by direct contact of a hot surface, hot air, hot fat, or radiation.
- Moist Cooking – a wet cooking technique where heat is applied through a liquid medium (stock, steam, boiling, poaching, etc.).
- Combination – a cooking technique that employs both dry and moist preparations, using one process to start and the other process to finish.
- Baking– using dry heat to cook food in an enclosed environment. Temperature range is generally up to 375.
- Roasting – almost the same method as baking, but roasting usually takes place on a lifted rack (to allow airflow from all directions, including the bottom), with the item being left uncovered, and at temperatures at 400 degrees or above.
- Sauté – a cooking process using high heat and a minimal amount of fat. Quick cooking.
- Stir-fry – an Asian dry cooking method. Similar to sautéing but a large high wall pan, or wok is used.
- Shallow-fry – the use of fat to transfer heat to food. Uses more fat than sautéing. Shallow-frying is typically a method that uses lower heat and in turn cooking time is longer. The level of fat should come halfway up the sides of the food being cooked.
- Grill – Using a radiant heat to cook food from below on grates. This includes gas, electric, charcoal or wood burning grills. Charcoal and wood-burning grills are a great way to add a smoky flavor to your food.
- Broiling – Similar to grilling. Broiling uses radiant heat from above. Temperatures for broiling are much higher than grilling.
- Poaching (140-180 degrees) – cooking food in a small amount of a liquid medium, such as a court bouillon.
- Simmering (180-205 degrees) – the cooking of food in a larger amount of a liquid, where the food is cooked by the gentle convection of the liquid.
Low Simmer - done on low heat. Great for stewing or for stocks - processes with long cooking times.
- Simmer - done on medium low heat. Great for thicker soups and stews. Maybe require more occasional stirring.
- Rapid Simmer - done on medium heat. Almost a full boil, but not quite. Great application for when reducing, or using reduction as a means of thickening. Contemporary pan sauces.
- Boiling (212 degrees, sea level) – the cooking of food in a liquid medium where the heat is higher than a poach or a simmer, and there is rapid convection of the liquid throughout the cooking process.
- Blanch – using boiling water to quickly par-cook ingredients to make them easier to eat or work with on another cooking method to finish them.
- Steam – using liquid that has turned into a vapor to cook ingredients in an enclosed environment.
- Deep-fry – food cooked by complete submersion in fat and heat transfer. Foods typically have a coating or breading that shelters the inside from falling out. There is a standard breading technique for deep-frying.
- Braising – a combination cooking method usually for larger cuts of meat. The meat is first browned on all sides, and then a liquid medium is added, generally 2/3 the way up the sides of the pan. The pan is then covered and cooked in the oven on a lower heat for many hours until the large tough muscle is broken down and very tender.
- Stewing – a combination cooking method usually for smaller cuts of tough meat. The meat is first browned on all sides and then a liquid medium is added the entire way up the cooking vessel, covered or uncovered, and cooked on the stove-top, usually on a simmer.
Now that we understand a little bit more about the cooking techniques, I'll break it down a step further with the method for each technique used and the heat method associated with it.
- Baking | Air | Dry
- Roasting | Air | Dry
- Sauté | Fat | Dry
- Stir-fry | Fat | Dry
- Shallow-fry | Fat | Dry
- Grill | Air | Dry
- Broil | Air | Dry
- Poach | Liquid | Moist
- Simmer | Liquid | Moist
- Boil | Liquid | Moist
- Blanch |Liquid |Moist
- Steam | Steam | Moist
- Deep-fry | Fat | DRY
- Braise | Fat, liquid | Combination
- Stewing | Fat, liquid | Combination
Time to mess you up a little bit. Look 3 lines above this one to Deep-Fry. Notice that it says that it is a DRY cooking technique? That's not a typo! Back to the temperature again... Water boils at a maximum (under regular conditions) at 212 degrees at sea level, 198 degrees here, not making it possible for the temperature to be hot enough for the reaction to occur. Deep-Frying however is done with oil, not water. Also, the most consistent temperature in which to fry, across the board is 350 degrees (remember above that this is the "sweet-spot"). This allows for the reaction to take place as even without a flame, the surrounding temperature of the food that is being submerged in the hot oil is sufficient enough to cause the reaction. Hey, if nothing else, that question + the provided explanation should win you a couple bets the next time you go to your local watering hole!
Well, as Forrest Gump would say, That's all I have to say about that. Between last week and this week, I have given you a lot, and I mean a lot of information to consider. I hope that someone out there finds all of this information useful! I promise that moving forward, posts will NOT be this long, and we are going to have a blast as we start breaking down the cues given off during the cooking process as it relates to our 5 senses. The theme of this weeks recipes is they all require heat... I hate it when I make it tough on myself :) Talk to you all next week!!
• 1 T. olive oil
• 1 rotisserie chicken, all meat removed from bone, diced or shredded
• 1 1⁄2 cups onions, chopped
• 6 garlic cloves, finely chopped
• 1 teaspoon fresh ginger, peeled and finely chopped
• 2 teaspoons ground cinnamon
• 1 teaspoon ground cumin
• 1 teaspoon ground coriander
• 1⁄2 teaspoon ground red pepper
• 1⁄2 teaspoon turmeric
• 1⁄4 teaspoon saffron, ground
• 1 cup chicken stock
• 2 tablespoons fresh coriander leaves, chopped
• 1 tablespoon fresh parsley leaves, chopped
• 7 large eggs, lightly beaten
• 1 teaspoon salt
• 1⁄2 teaspoon ground black pepper
• 1 lb phyllo dough, thawed (about 24 leaves)
• 1 cup butter (2 sticks)
1. In a large skillet, add onions, garlic, ginger, and 1 tablespoon oil; saute, stirring constantly, just until onions are translucent. Stir in cinnamon, cumin, ground coriander, red pepper, turmeric, and saffron. Reduce heat to low and cook, stirring constantly, until onions are completely coated with spices-about 3 minutes.
2. Increase heat to high. Add broth, fresh coriander, and parsley to skillet with onion mixture. Heat to boiling, stirring to combine. Add chicken to skillet, cover, reduce heat to low, and simmer for 10 minutes.
3. Add eggs, salt, and pepper to onion mixture. Cook until soft curds form, about 3 minutes. Remove skillet from heat and set onion-egg mixture aside to cool.
4. To assemble b’stilla, place phyllo between 2 sheets of waxed paper, then cover with damp towel. (Phyllo dries out very quickly. Each time you remove a sheet, be sure to cover remaining sheets with damp towel.) Brush 12-inch pizza pan with some melted butter. Remove 1 sheet of Phyllo and place on pan, letting the edges hang over the rim. Brush phyllo sheet with butter. Working quickly, stack and butter 11 more sheets, arranging them in the pan in an overlapping, circular fashion (like a pinwheel).
5. On center of phyllo, in even layers, arrange half the Topping, half of onion-egg mixture, all of chicken pieces, the remaining onion-egg mixture, and the remaining Topping, Fold overhanging phyllo over top of b’stilla and brush top with butter.
6. Continue to butter and arrange 12 phyllo sheets in the same pinwheel fashion over top of b’stilla (as before). Carefully tuck the overhanging ends underneath it. Brush top and side of b’stilla with butter. Cover loosely with foil.(At this point, can be refrigerated two hours or up to 2 days before baking).
7. Heat oven to 350 degrees F. Bake b’stilla 20 minutes or until golden. (If b’stilla has been chilled, bake 5 to 10 minutes longer.) Place a baking sheet or another 12-inch pizza pan over the b’stilla and invert so that the underside is now on top. Return to oven on the new pan (or slide back onto original pan) and bake 25 minutes longer or until crisp and golden.
8. If desired, sprinkle confectioners' sugar and ground cinnamon on top of b’stilla.
Topping:. Heat oven to 375 degrees F. Spread almonds on ungreased baking sheet and place in oven for 7 minutes or until lightly toasted. In food processor with chopping blade (or by hand), process almonds with sugar and cinnamon until coarsely ground.
