MANKIND HAS ENJOYED A WHOLE NEW SET OF FOOD FLAVORS SINCE CAVEMEN FIRST SET UP CAMPFIRES AND STARTED ROASTING THEIR KILL. (kitchen oven)
Cooking is the process of applying heat to food to modify it through chemical and physical reactions that improve flavour, lower the risk of foodborne illness, and boost nutritional content.
From a gastronomic standpoint, the more intriguing and pleasurable changes occur when food compounds experience the chemical reactions listed below:
Denaturation of proteins (kitchen oven)
The natural form of a protein is the three-dimensional structure (conformation) that it assumes when it functions normally. The protein is said to be denature when this structure is broken (usually by heat or acid). Proteins’ flavour and texture are also affect by changes in their form.
Different proteins denature at different temperatures; most dietary proteins denature between 120°F and 160°F (49°C and 71°C). Denatured proteins, such as egg whites, begin to denature at 141°F / 61°C and turn white because their form is no longer transparent to visible light. Around 122°F / 50°C, the protein myosin begins to denature in flesh; around 150°F / 65.5°C, another protein, actin, begins to denature. The majority of people prefer meat cooked in such a way that the myosin is denature but the actin remains intact.
The Maillard process is a chemical reaction that occurs when food
A Maillard reaction is a browning event that imparts a fragrant and mouthwatering scent to meals. This occurs when an amino acid and certain types of sugars break down and subsequently recombine into hundreds of other sorts of molecules, which is usually initiate by heat. The specific byproducts and odours produced are determine by the amino acids present in the meal being cook, but imagine the rich aroma of crispy skin on roasted chicken.
The reaction is most visible for culinary purposes around 310°F / 154°C, though the rate depends on pH, chemical reagents in the food, and the amount of time spent at any particular temperature. Many meats are roast at 325°F / 160°C or higher; at lower temperatures, the Maillard process does not occur.
Caramelization (kitchen oven)
Caramelization is cause by the breakdown of carbohydrates, which, like the Maillard reaction, produces hundreds of odor-producing chemicals. Only the middle range of 356–370°F / 180–188°C produces rich flavours when pure sucrose (the type of sugar in granulated sugar) caramelises at 320–400°F / 160–204°C.
In baking, foods baked at 375°F / 190°C have a clearly browned surface, whilst those done at or below 350°F / 175°C have a lighter-colored outside.
“That’s great,” you’re presumably thinking, “but how does any of this help me cook?”
Understanding what reactions you want to induce and then recognising when those reactions have occurred is how you can know when something is done cooking. Are you preparing a steak? With a thermometer, check the interior temperature; once it reaches 140°F / 60°C, the myosin proteins will have begun to denature. Do you want to bake crispy chocolate chip cookies at 375°F/190°C? Open your eyes and keep your nose open; you’ll know the cookies are about done when they start to turn brown and you can smell the caramelization. That’s all there is to it. Foods are considered “done” once they have reached a specific state and have undergone the appropriate chemical processes. Remove the food from the oven as soon as the reactions have occurred; it is done cooking.
Learn To Cook
Learn to cook with all of your senses: smell, touch, sight, sound, and taste. Meat that has been cook until it is medium rare—when myosin has denatured but actin has not yet denatured—feels stiffer and shrinks significantly. Once the water has mostly evaporated, the bubbling sound of a sauce being boil and reduced will sound different, as bubbles pushing up through the thicker liquid will have a different sound. Bread crust that has reached the temperatures required for Maillard reactions and caramelization will smell great and turn golden brown in colour. By extension, this means that the bread’s crust must achieve a temperature of 310°F / 155°C before it starts to brown, which you may check using an infrared thermometer. (Because bread flour contains both proteins and sugars, baking causes both caramelization and Maillard processes.)
This chapter explains when and how these changes happen so you can confidently say, “It’s done!” We’ll begin by examining the distinctions between the most frequent sources of heat in cooking, as well as how variations in heat and temperature affect cooking. Because one of the main reasons for cooking is to reduce the risk of foodborne disease, we’ll also go over the key challenges in food safety, including how to deal with bacterial contamination and parasites, as well as some sample recipes to exemplify the ideas. The rest of the chapter will then look at a variety of critical temperature points, starting with the coldest and working up to the hottest, highlighting the relevance of each and providing sample recipes to demonstrate the reactions that occur at each of these degrees.

The recipes in this section, like the rest of the book, are components rather than complete dinners or meals. Make as many combinations as you want! It’s normally easier to cook each component of a dish separately, such as vegetables in one pan, meats or proteins in another, and carbohydrates in a third. This allows you to isolate the variables for each component before finally combining them. If you’re new to cooking, Eggplant Parmesan may be your favourite dish, but it’s definitely not the ideal place to start learning about the reactions that occur.
Finally, coding and product development share an assumption with cooking and baking: it’s do when it’s do, not when the timer goes off. One of the best culinary suggestions I can give is to “calibrate” yourself: make a guess if something is do and then double-check, noting what your senses, particularly scent and sight, observe during the process.
