Cooking, also known as cookery or professionally as the culinary arts, is the art, science and craft of using heat to make food more palatable, digestible, nutritious, or safe. Cooking techniques and ingredients vary widely, from grilling food over an open fire, to using electric stoves, to baking in various types of ovens, reflecting local conditions. Cooking is an aspect of all human societies and a cultural universal.
A thermometer is a device that measures temperature or temperature gradient. A thermometer has two important elements: (1) a temperature sensor in which some change occurs with a change in temperature; and (2) some means of converting this change into a numerical value. Thermometers are widely used in technology and industry to monitor processes, in meteorology, in medicine, and in scientific research.
Confectionery is the art of making confections, which are food items that are rich in sugar and carbohydrates. Exact definitions are difficult. In general, however, confectionery is divided into two broad and somewhat overlapping categories: bakers' confections and sugar confections. The occupation of confectioner encompasses the categories of cooking performed by both the French patissier and the confiseur.
Baking is a method of preparing food that uses dry heat, typically in an oven, but can also be done in hot ashes, or on hot stones. The most common baked item is bread, but many other types of foods can be baked. Heat is gradually transferred "from the surface of cakes, cookies, and pieces of bread to their center, typically conducted at elevated temperatures surpassing 300°F. Dry heat cooking imparts a distinctive richness to foods through the processes of caramelization and surface browning. As heat travels through, it transforms batters and doughs into baked goods and more with a firm dry crust and a softer center. Baking can be combined with grilling to produce a hybrid barbecue variant by using both methods simultaneously, or one after the other. Baking is related to barbecuing because the concept of the masonry oven is similar to that of a smoke pit.
In recipes, quantities of ingredients may be specified by mass, by volume, or by count.
Caramel is an orange-brown confectionery product made by heating a range of sugars. It can be used as a flavoring in puddings and desserts, as a filling in bonbons or candy bars, or as a topping for ice cream and custard.
Searing or pan searing is a technique used in grilling, baking, braising, roasting, sautéing, and the like, in which the surface of the food is cooked at high temperature until a browned crust forms. Similar techniques, such as browning and blackening, are typically used to sear all sides of a particular piece of meat, fish, poultry, etc. before finishing it in the oven. To obtain the desired brown or black crust, the meat surface must exceed 150 °C (300 °F), so searing requires the meat surface be free of water, which boils at around 100 °C (212 °F).
A chocolate brownie, or simply a brownie, is a chocolate baked confection. Brownies come in a variety of forms and may be either fudgy or cakey, depending on their density. Brownies often, but not always, have a glossy "skin" on their upper crust. They may also include nuts, frosting, chocolate chips, or other ingredients. A variation made with brown sugar and vanilla rather than chocolate in the batter is called a blond brownie or blondie. The brownie was developed in the United States at the end of the 19th century and popularized there during the first half of the 20th century.
Fudge is a type of confection that is made by mixing sugar, butter and milk. It has its origins in the 19th century United States, and was popular in the women's colleges of the time. Fudge can come in a variety of flavorings depending on the region or country it was made; popular flavors include fruit, nut, chocolate and caramel. Fudge is often bought as a gift from a gift shop in tourist areas and attractions.
Stock, sometimes called bone broth, is a savory cooking liquid that forms the basis of many dishes – particularly soups, stews, and sauces. Making stock involves simmering animal bones, meat, seafood, or vegetables in water or wine, often for an extended period. Mirepoix or other aromatics may be added for more flavor.
Fannie Merritt Farmer was an American culinary expert whose Boston Cooking-School Cook Book became a widely used culinary text.
Sous vide, also known as low-temperature, long-time (LTLT) cooking, is a method of cooking invented by the French chef Georges Pralus in 1974, in which food is placed in a plastic pouch or a glass jar and cooked in a water bath for longer than usual cooking times at a precisely regulated temperature.
A meat thermometer or cooking thermometer is a thermometer used to measure the internal temperature of meat, especially roasts and steaks, and other cooked foods. The degree of "doneness" of meat or bread correlates closely with the internal temperature, so that a thermometer reading indicates when it is cooked as desired. When cooking, food should always be cooked so that the interior reaches a temperature sufficient, that in the case of meat is enough to kill pathogens that may cause foodborne illness or, in the case of bread, that is done baking; the thermometer helps to ensure this.
Corn chowder is a chowder soup prepared using corn as a primary ingredient. Basic corn chowder is commonly made of corn, onion, celery, milk or cream, and butter. Additional ingredients sometimes used include potatoes or squash, salt pork, fish, seafood and chicken. In the United States, recipes for corn chowder date to at least as early as 1884. Corn chowder is mass-produced as a canned food in the U.S.
The Boston Cooking-School Cook Book (1896) by Fannie Farmer is a 19th-century general reference cookbook which is still available both in reprint and in updated form. It was particularly notable for a more rigorous approach to recipe writing than had been common up to that point.
Low-temperature cooking is a cooking technique that uses temperatures in the range of about 60 to 90 °C for a prolonged time to cook food. Low-temperature cooking methods include sous vide cooking, slow cooking using a slow cooker, cooking in a normal oven which has a minimal setting of about 70 °C (158 °F), and using a combi steamer providing exact temperature control. The traditional cooking pit also cooks food at low temperature.
Duchess potatoes consist of a purée of mashed potato, egg yolk, and butter, which is forced from a piping bag or hand-moulded into various shapes which are then baked in a high temperature oven until golden. They are typically seasoned similarly to mashed potatoes with, for example, salt, pepper, and nutmeg. They are a classic item of French cuisine, and are found in historic French cookbooks.
Candy making or candymaking is the preparation and cookery of candies and sugar confections. Candy making includes the preparation of many various candies, such as hard candies, jelly beans, gumdrops, taffy, liquorice, cotton candy, chocolates and chocolate truffles, dragées, fudge, caramel candy, and toffee.
An oatmeal raisin cookie is a type of drop cookie made from an oatmeal-based dough with raisins. Its ingredients also typically include flour, sugar, eggs, salt, and spices.
