Curd in the context of Vinegar

Cheese is a type of dairy product produced in a range of flavors, textures, and forms by coagulation of the milk protein casein. It is composed of proteins and fat from milk, usually of cows, goats or sheep, and sometimes of water buffalo. During production, milk is usually acidified and either the enzymes of 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, 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 pasteurised, 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. Other added ingredients may include black pepper, garlic, chives or cranberries. A cheesemonger, or specialist seller of cheeses, may have expertise with selecting, purchasing, receiving, storing and ripening cheeses.

Tofu (Japanese: 豆腐, Hepburn: Tōfu; Korean: 두부; RR: dubu, Chinese: 豆腐; pinyin: dòufu) or bean curd is a food prepared by coagulating soy milk and then pressing the resulting curds into solid white blocks of varying softness: silken, soft, firm, and extra (or super) firm. It originated in China and has been consumed for over 2,000 years. Tofu is a traditional component of many East Asian and Southeast Asian cuisines; in modern Western cooking, it is often used as a meat substitute.

Nutritionally, tofu is low in calories, while containing a relatively large amount of protein. It is a high and reliable source of iron, and can have a high calcium or magnesium content depending on the coagulants (e.g. calcium chloride, calcium sulfate, magnesium sulfate) used in manufacturing. Cultivation of tofu, as a protein-rich food source, has one of the lowest needs for land use (1.3 m/ 1000 kcal) and emits some of the lowest amount of greenhouse gas emissions (1.6 kg CO₂/ 100 g protein).

Scrambled eggs is a culinary dish made from eggs (usually chicken eggs), where the whites and yolks have been stirred, whipped, or beaten together (typically with the addition of other ingredients), then heated so that the proteins denature and coagulate, and they form into "curds".

Quark or quarg (sometimes translated as curd cheese) is a type of fresh dairy product made from milk. The milk is soured, usually by adding lactic acid bacteria cultures, and strained once the desired curdling is achieved. It can be classified as fresh acid-set cheese. Traditional quark can be made without rennet, but in modern dairies small quantities of rennet are typically added. It is soft, white and unaged, and usually has no salt added.

Quark and its dryer variant tvorog are traditional in the cuisines of Baltic, Germanic and Slavic-speaking countries as well as amongst French, Romanians, Italians, Hungarians, Greeks, Ashkenazi Jews and various Turkic peoples. Quark is similar to other fresh cheeses including the French fromage blanc, cottage cheese, and farmer cheese.

Granular cheese, also known as stirred curd cheese and hard cheese, is a type of cheese produced by repeatedly stirring and draining a mixture of curd and whey. It can refer to a wide variety of cheeses, including the grana cheeses such as Parmigiano Reggiano and various others.
