Vegetables, fruits, grains and nuts as well as herbs and [[spice]]s come from plants, while meat, eggs, and dairy products come from animals. Mushrooms and the yeast used in baking are kinds of [[fungi]]. Cooks also use [[water]] and [[mineral]]s such as [[salt]]. Cooks can also use [[wine]] or [[Distilled beverage|spirits]]. [28] => [29] => Naturally occurring ingredients contain various amounts of molecules called ''[[Protein (nutrient)|proteins]]'', ''[[carbohydrate]]s'' and ''[[fat]]s''.

Similarly, the heating of sugars and proteins causes the [[Maillard reaction]], a basic flavor-enhancing technique. [36] => [37] => An [[emulsion]] of starch with fat or water can, when gently heated, provide thickening to the dish being cooked. In [[European cuisine|European]] cooking, a mixture of butter and flour called a [[roux]] is used to thicken liquids to make stews or sauces.{{Cite web|url=https://guide.michelin.com/sg/dining-in/what-is-roux-sg/news|title=What is...roux?|website=MICHELIN Guide|language=en|access-date=2019-02-04}} In Asian cooking, a similar effect is obtained from a mixture of rice or [[corn starch]] and water. These techniques rely on the properties of starches to create simpler mucilaginous [[saccharide]]s during cooking, which causes the familiar thickening of [[sauce]]s.

Fats are used in a number of ways in cooking and baking. To prepare [[stir fry|stir fries]], [[grilled cheese]] or [[pancake]]s, the pan or griddle is often coated with fat or oil. Fats are also used as an ingredient in baked goods such as cookies, cakes and pies. Fats can reach temperatures higher than the boiling point of water, and are often used to conduct high heat to other ingredients, such as in frying, deep frying or sautéing. Fats are used to add flavor to food (e.g., butter or bacon fat), prevent food from sticking to pans and create a desirable texture.

It is a fundamental human activity that has been practiced for centuries, and it involves various techniques and methods depending on the culture, region, and available ingredients. Cooking not only transforms raw food into a more palatable and digestible form but also enhances its flavor, texture, and nutritional value. It can be performed in a variety of settings, from home kitchens to professional restaurants and catered events. This Wikipedia page provides a comprehensive overview of cooking, including its history, techniques, utensils, and cultural significance across different societies. It also explores different cuisines and their individual cooking styles, as well as modern advancements in cooking technology and trends like molecular gastronomy. Additionally, the page covers various aspects related to the art of cooking, such as recipe development, meal planning, and food safety. The page serves as a valuable resource for anyone interested in learning about the art and science behind food preparation and the diverse practices that have shaped culinary traditions across the globe.
