Curdle
Curdling is the breaking of an emulsion or colloid into large parts of different composition through the physio-chemical processes of flocculation, creaming, and coalescence. Curdling is purposeful in the production of cheese curd and tofu; undesirable in the production of a sauce, cheese fondue or a custard. Method In curdling, the pH of the milk decreases and becomes more acidic. Independently floating casein molecules attract one another, forming "curdles" that float in a translucent whey. At warmer temperatures, the clumping reaction occurs more quickly than at colder temperature. Curdling occurs naturally if cows' milk is left open in a warm environment to air for a few days. Cheese and tofu Milk and soy milk are curdled intentionally to make cheese and tofu by the addition of enzymes (typically rennet), acids (including lemon juice), or various salts (magnesium chloride, calcium chloride, or gypsum); the resulting curds are then pressed.

Tofu
Tofu (), also known as bean curd in English, is a food prepared by coagulating soy milk and then pressing the resulting curds into solid white blocks of varying softness; it can be ''silken'', ''soft'', ''firm'', ''extra firm'' or ''super firm''. Beyond these broad textural categories, there are many varieties of tofu. It has a subtle flavor, so it can be used in savory and sweet dishes. It is often seasoned or marinated to suit the dish and its flavors, and due to its spongy texture, it absorbs flavors well. It is a traditional component of East Asian and Southeast Asian cuisines, and has been consumed in China for over 2,000 years. In modern western cooking, it is most often treated as a meat substitute. Nutritionally, tofu is low in calories, while containing a relatively large amount of protein. It is high in iron, and can have a high calcium or magnesium content depending on the coagulants (e.g. calcium chloride, calcium sulphate, magnesium sulphate) used in manufacturi ...

Curd
Curd is obtained by coagulating milk in a sequential process called curdling. It can be a final dairy product or the first stage in cheesemaking. The coagulation can be caused by adding rennet or any edible acidic substance such as lemon juice or vinegar, and then allowing it to coagulate. The increased acidity causes the milk proteins (casein) to tangle into solid masses, or ''curds''. Milk that has been left to sour (raw milk alone or pasteurized milk with added lactic acid bacteria) will also naturally produce curds, and sour milk cheeses are produced this way. Producing cheese curds is one of the first steps in cheesemaking; the curds are pressed and drained to varying amounts for different styles of cheese and different secondary agents (molds for blue cheeses, etc.) are introduced before the desired aging finishes the cheese. The remaining liquid, which contains only whey proteins, is the whey. In cow's milk, 90 percent of the proteins are caseins. Curds can be used i ...

Cheese
Cheese is a dairy product produced in wide ranges of flavors, textures, and forms by coagulation of the milk protein casein. It comprises proteins and fat from milk, usually the milk of cows, buffalo, goats, or sheep. During production, milk is usually acidified and the enzymes of either rennet or bacterial enzymes with similar activity are added to cause the casein to coagulate. The solid curds are then separated from the liquid whey and pressed into finished cheese. Some cheeses have aromatic molds on the rind, the outer layer, or throughout. Over a thousand types of cheese exist and are produced in various countries. Their styles, textures and flavors depend on the origin of the milk (including the animal's diet), whether they have been pasteurized, the butterfat content, the bacteria and mold, the processing, and how long they have been aged. Herbs, spices, or wood smoke may be used as flavoring agents. The yellow to red color of many cheeses is produced by adding a ...

Custard
Custard is a variety of culinary preparations based on sweetened milk, cheese, or cream cooked with egg or egg yolk to thicken it, and sometimes also flour, corn starch, or gelatin. Depending on the recipe, custard may vary in consistency from a thin pouring sauce (''crème anglaise'') to the thick pastry cream (''crème pâtissière'') used to fill éclairs. The most common custards are used in custard desserts or dessert sauces and typically include sugar and vanilla; however, savory custards are also found, e.g., in quiche. Custard is usually cooked in a double boiler (bain-marie), or heated very gently in a saucepan on a stove, though custard can also be steamed, baked in the oven with or without a water bath, or even cooked in a pressure cooker. Custard preparation is a delicate operation, because a temperature increase of 3–6 °C (5–10 °F) leads to overcooking and curdling. Generally, a fully cooked custard should not exceed 80 °C (~175 °F) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hollandaise
Hollandaise sauce ( or ; ), also called Dutch sauce, is a mixture of egg yolk, melted butter, and lemon juice (or a white wine or vinegar reduction). It is usually seasoned with salt, and either white pepper or cayenne pepper. It is well known as a key ingredient of eggs Benedict, and is often served on vegetables such as steamed asparagus. Origins ''Sauce hollandaise'' is French for "Hollandic sauce". The name implies Dutch origins, but the actual connection is unclear. The name "Dutch sauce" is documented in English as early as 1573, though without a recipe showing that it was the same thing. The first documented recipe is from 1651 in La Varenne's ''Le Cuisinier François'' for "asparagus with fragrant sauce": Not much later, in 1667, a similar Dutch recipe was published. There is a popular theory that the name comes from a recipe that the French Huguenots brought back from their exile in Holland. La Varenne is credited with bringing sauces out of the Middle Ages ...

Whey
Whey is the liquid remaining after milk has been curdled and strained. It is a byproduct of the manufacturing of cheese or casein and has several commercial uses. Sweet whey is a byproduct resulting from the manufacture of rennet types of hard cheese, like cheddar or Swiss cheese. Acid whey (also known as sour whey) is a byproduct brought out during the making of acid types of dairy products, such as strained yogurt. Whey proteins consist of α-lactalbumin, β-lactoglobulin, serum albumin, immunoglobulins, and proteose peptones. Composition Whey protein is the collection of globular proteins isolated from whey. The protein in cow's milk is 20% whey protein and 80% casein protein, whereas the protein in human milk is 60% whey and 40% casein. The protein fraction in whey constitutes approximately 10% of the total dry solids in whey. This protein is typically a mixture of beta-lactoglobulin (~48-58%), alpha-lactalbumin (~13-19%), bovine serum albumin (~6%)(see also serum albumi ...

Strained Yogurt
Strained yogurt, Greek yogurt, yogurt cheese, sack yogurt, or kerned yogurt is yogurt that has been strained to remove most of its whey, resulting in a thicker consistency than normal unstrained yogurt, while still preserving the distinctive sour taste of yogurt. Like many types, strained yogurt is often made from milk enriched by boiling off some water content, or by adding extra butterfat and powdered milk. In Europe and North America, it is often made from low-fat or fat-free cow's milk. In Iceland, a similar product named skyr is made. Strained yogurt is generally marketed in North America as "Greek yogurt" and in the UK as "Greek-style yogurt", though strained yogurt is also widely eaten in Levantine, Eastern Mediterranean, Middle Eastern, Central Asian and South Asian cuisines, where it is often used in cooking, as it curdles less readily when cooked. It is used in a variety of dishes, cooked or raw, savory or sweet. Straining makes even nonfat varieties thicker, rich ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fondue
Fondue (, , ) is a Swiss melted cheese dish served in a communal pot ( ''caquelon'' or fondue pot) over a portable stove () heated with a candle or spirit lamp, and eaten by dipping bread into the cheese using long-stemmed forks. It was promoted as a Swiss national dish by the Swiss Cheese Union (Schweizerische Käseunion) in the 1930s, and was popularized in North America in the 1960s. Since the 1950s, the term "fondue" has been generalized to other dishes in which a food is dipped into a communal pot of liquid kept hot in a fondue pot: chocolate fondue, ''fondue au chocolat'', in which pieces of fruit or pastry are dipped into a melted chocolate mixture, and ''fondue bourguignonne'', in which pieces of meat are cooked in hot oil or broth. Etymology The word ''fondue'' is the feminine passive past participle of the French verb 'to melt' used as a noun. It is first attested in French in 1735, in Vincent La Chapelle's ''Cuisinier moderne'',Vincent la Chapelle, ''Le cuisinier ...

Yogurt
Yogurt (; , from tr, yoğurt, also spelled yoghurt, yogourt or yoghourt) is a food produced by bacterial Fermentation (food), fermentation of milk. The bacteria used to make yogurt are known as ''yogurt cultures''. Fermentation of sugars in the milk by these bacteria produces lactic acid, which acts on milk protein to give yogurt its texture (food), texture and characteristic tart flavor. Cow's milk is the milk most commonly used to make yogurt. Milk from water buffalo, goats, sheep, ewes, mares, camels, and yaks are also used to produce yogurt. The milk used may be Milk#Creaming and homogenization, homogenized or not. It may be pasteurized or raw milk, raw. Each type of milk produces substantially different results. Yogurt is produced using a culture of Lactobacillus delbrueckii subsp. bulgaricus, ''Lactobacillus delbrueckii'' subsp. ''bulgaricus'' and ''Streptococcus thermophilus'' bacteria. In addition, other Lactobacillus, lactobacilli and Bifidobacterium, bifidobacteria a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
