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. [1] The coagulation can be caused by adding rennet, a culture, 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.

Contents

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 in baking or may be consumed as a snack.

In England, curds produced using rennet are referred to as junket, it has a texture similar to pudding or jelly. Junket are dessert like pudding as well decorated with ingredients such as  semolina, raisins, chopped nuts and other ingredients. This can be baked, or the curd pudding can be used to bake thin custard pancakes. [2]

Cheese curds, drained of the whey and served without further processing or aging, are popular in some French-speaking regions of Canada, such as Quebec, parts of Ontario, and Atlantic Canada. These are often sold in snack-sized packaging and seen as a typically Canadian food item. Throughout Canada cheese curds are served with french fries and gravy in a popular snack called poutine .

Curds are also typical of some Germanic-descent regions such as historic Waterloo County in Ontario. [3]

In some parts of the Midwestern U.S., especially in Wisconsin, curds are eaten fresh without further additions, or they are breaded and fried.

Curd products vary by region and include cottage cheese, curd cheese (both curdled by bacteria and sometimes also rennet), farmer cheese, pot cheese, queso blanco , and paneer. The word can also refer to a non-dairy substance of similar appearance or consistency, though in these cases a modifier or the word 'curdled' is generally used.

Hungary has a form of curds called túró, which is an ingredient in several national dishes, such as túrós palacsinta, túrós csusza and túrógombóc. [4] In 2019, rögös túró — a form that has a unique texture "consisting of clumps of loose lumps reminiscent of cauliflower" (the name translates to "lumpy túró") — was granted the status of Traditional Speciality Guaranteed (TSG) by the EU. [5]

In Turkey, curds are called keş and are served on fried bread and are also eaten with macaroni in the provinces of Bolu and Zonguldak.

In Sri Lanka, curd is eaten fresh as a dessert since antiquity. Usually buffalo curd cured in clay pots and served with kitul treacle (Caryota urens), is considered a delicacy in almost every part of the island. Although cows milk curd also is produced, Buffalo curd is the preferred variety.

In Nepal, curd is produced by souring pasteurized milk with natural micro-flora. The pasteurized milk is added to a container called theki carved out of wood like Daar(Boehmeria Rugulosa). The milk is left for 12–16 hours and the micro-organisms entrapped within the Theki act as inocula. [6] The curd produced after is used to make chhurpi and variations of it.

In Mexico, chongos zamoranos is a dessert prepared with milk curdled with sugar and cinnamon.

Albanian gjiza is made by boiling whey for about 15 minutes and adding vinegar or lemon. The derivative is drained and salted to taste. Gjiza can be served immediately or refrigerated for a couple of days.

<span class="mw-page-title-main">Whey</span> Liquid remaining after milk has been curdled and strained

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 is a byproduct brought out during the making of acid types of dairy products, such as strained yogurt.

Cottage cheese is a curdled milk product with a mild flavour and a creamy, heterogeneous, soupy texture, made from skimmed milk. An essential step in the manufacturing process distinguishing cottage cheese from other fresh cheeses is the addition of a "dressing" to the curd grains, usually cream, which is mainly responsible for the taste of the product. Cottage cheese is not aged.

Cheese is a dairy product produced in a range of flavors, textures, and forms by coagulation of the milk protein casein. It comprises proteins and fat from milk. 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.
