Souring
Souring is a food preparation technique that causes a physical and chemical change in food by exposing it to an acid. This acid can be added explicitly (e.g., vinegar, lemon juice, lime juice, etc.), or can be produced within the food itself by a microbe, such as ''Lactobacillus''. Souring is similar to pickling or fermentation, but souring typically occurs in minutes or hours, while pickling and fermentation can take a much longer amount of time. Examples Dairy products produced by souring include: Clabber, Cheese, ''Crème fraîche'', Cultured buttermilk, Curd, ''Filmjölk'', ''Kefir'', '' Paneer'', ''Smetana'', Soured milk, Sour cream, and Yogurt. Grain products include: Idli, Sourdough, and Sour mash. Others foods produced by souring include: '' Ceviche'', ''Kinilaw'', and Key lime pie. See also * Fermented milk products * Food preservation * Marination Marinating is the process of soaking foods in a Seasoning, seasoned, often acidic, liquid before cooking. This sa ...

Kinilaw
''Kinilaw'' ( or , literally "eaten raw") is a raw seafood dish and preparation method native to the Philippines. It is more accurately a cooking process that relies on vinegar and acidic fruit juices (usually citrus) to denature the ingredients, rather than a dish, as it can also be used to prepare meat and vegetables. Kinilaw dishes are usually eaten as appetizers before a meal, or as finger food () with alcoholic drinks. Kinilaw is also sometimes called ''kilawin'', especially in the northern Philippines, but the term ''kilawin'' more commonly applies to a similar lightly grilled meat dish. Description The most common kinilaw dish is ''kinilaw na isda'' ("fish ''kinilaw''"), prepared using raw cubed fish mixed with vinegar (usually coconut vinegar or cane vinegar) as the primary denaturing agent; along with a souring agent to enhance the tartness like ''calamansi'', '' dayap'' (key lime), '' biasong'' (also known as ''suhà''), '' kamias'' (bilimbi), tamarind, green ...

Sour Cream
Sour cream (sometimes known as soured cream in British English) is a dairy product obtained by fermenting regular cream with certain kinds of lactic acid bacteria. The bacterial culture, which is introduced either deliberately or naturally, sours and thickens the cream. Its name comes from the production of lactic acid by bacterial fermentation, which is called souring. Crème fraîche is one type of sour cream with a high fat content and less sour taste. Traditional Traditionally, sour cream was made by letting cream that was skimmed off the top of milk ferment at a moderate temperature. It can also be prepared by the souring of pasteurized cream with acid-producing bacterial culture. The bacteria that developed during fermentation thickened the cream and made it more acidic, a natural way of preserving it. Commercial varieties According to US ( FDA) regulations, commercially produced sour cream contains no less than 18% milkfat before bulking agents are added, a ...

Food Preservation
Food preservation includes processes that make food more resistant to microorganism growth and slow the redox, oxidation of fats. This slows down the decomposition and rancidification process. Food preservation may also include processes that inhibit visual deterioration, such as the enzymatic browning reaction in apples after they are cut during food preparation. By preserving food, food waste can be reduced, which is an important way to decrease production costs and increase the efficiency of food systems, improve food security and nutrition and contribute towards environmental sustainability. For instance, it can reduce the Environmental impact of agriculture, environmental impact of food production. Many processes designed to preserve food involve more than one food preservation method. Preserving fruit by turning it into jam, for example, involves boiling (to reduce the fruit's moisture content and to kill bacteria, etc.), sugaring (to prevent their re-growth) and sealing wi ...

Sourdough
Sourdough is a type of bread that uses the fermentation by naturally occurring yeast and lactobacillus bacteria to raise the dough. In addition to leavening the bread, the fermentation process produces lactic acid, which gives the bread its distinctive sour taste and improves its keeping-qualities. History Sourdough is one of the most ancient forms of bread. It was the standard method of breadmaking for most of human history until the Middle Ages, when it was replaced by barm. Barm, in turn, was replaced in the late 19th and early 20th centuries by industrially produced baker's yeast. The ''Encyclopedia of Food Microbiology'' states: "One of the oldest sourdough breads dates from 3700 BCE and was excavated in Switzerland, but the origin of sourdough fermentation likely relates to the origin of agriculture in the Fertile Crescent and Egypt several thousand years earlier", and "Bread production relied on the use of sourdough as a leavening agent for most of human history; the ...

Cheese
Cheese is a type of 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 (usually the milk of cows, buffalo, goats or sheep). 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, ...

Smetana (dairy Product)
Smetana is the English-language name for the different types of sour cream traditionally prevalent in Central Europe, Central, Eastern Europe, Eastern, and Southeastern Europe, and Central Asia. It is a dairy product produced by souring heavy cream. It is similar to ''crème fraîche'', but nowadays mainly sold with 9% to 42% milkfat content depending on the country. Its cooking properties are different from ''crème fraîche'' and the lighter sour creams sold in the US, which contain 12 to 16% butterfat. It is widely used in cooking and baking. In some of the Slavic languages (Czech language, Czech, Slovak language, Slovak, Slovene language, Slovenian) the sole word smetana refers to (sweet) cream. In these cases an adjective (zakysaná, kyslá, kisla) meaning 'soured' is needed when referring to smetana in the English sense. Uses and distribution Smetana is used in Central, Southeastern, and Eastern European cuisines in appetizers, main courses, soups and desserts. For examp ...

Curd
Curd is obtained by Denaturation (biochemistry), 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, a Kefir cheese, 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. 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 ...

Paneer
Paneer (), is a fresh acid-set cheese, common in cuisine of South Asia, made from cow milk or buffalo milk. It is a non-aged, non-melting soft cheese made by curdling milk with a fruit- or vegetable-derived acid, such as lemon juice. Paneer was predominantly used in most north Indian dishes and is now commonly used throughout India due to its versatility as an ingredient in diverse dishes. Etymology The word ''paneer'' entered English from the Hindi-Urdu term ''panīr'', which comes from Persian () 'cheese', which comes from Old Iranian. Armenian (), Azerbaijani , Bengali ''ponir'' (পনির), Turkish and Turkmen , all derived from Persian , also refer to cheese of any type. History The origin of paneer is debated. Ancient Indian, Afghan, Iranian and Portuguese origins have been proposed for paneer. Legends about Krishna make several references to milk, butter, ghee and dahi (yogurt), but do not mention sour milk cheese. According to Arthur Berriedal ...

Fermented Milk Products
Fermented milk products or fermented dairy products, also known as cultured dairy foods, cultured dairy products, or cultured milk products, are dairy foods that have been made by fermenting milk with lactic acid bacteria such as ''Lactobacillus ''Lactobacillus'' is a genus of gram-positive, aerotolerant anaerobes or microaerophilic, rod-shaped, non-spore-forming bacteria. Until 2020, the genus ''Lactobacillus'' comprised over 260 phylogenetically, ecologically, and metabolically div ...'', '' Lactococcus'', and '' Leuconostoc''. The fermentation process increases the shelf life of the product while enhancing its taste and improving the digestibility of its milk. There is evidence that fermented milk products have been produced since around 10,000 BC. A range of different Lactobacilli strains has been grown in laboratories allowing for many cultured milk products with different flavors and characteristics. These bacteria allow the production of many fermented milks ...

Key Lime Pie
Key lime pie is an American dessert pie. It is made of Key lime juice, egg yolks, and sweetened condensed milk. It may be served with no topping, with a meringue topping made from egg whites, or with whipped cream. Traditionally, Key lime pie is made using a graham cracker crust. It may be made with or without baking in a Crust (baking), pie crust or without crust. The dish is named after the small Key limes, which are more aromatic than the common Persian limes, and which have yellow juice. The filling in a Key lime pie is typically yellow because of the egg yolks. The filling is made similarly to a Magic Lemon cream pie, by mixing the ingredients without cooking: the proteins of the egg yolks and condensed milk and the acidic lime juice curdle, thickening the mixture without baking. The pies are usually baked to pasteurize the eggs and thicken the filling further. History Key lime pie is probably derived from the "Magic Lemon Cream Pie" published in a promotional brochure by ...

Ceviche
Ceviche, cebiche, sebiche, or seviche () is a cold dish consisting of fish or shellfish marinated in citrus and seasonings. Different versions of ceviche are part of the culinary cultures of various Latin American countries along the Pacific Ocean where each one is native, including Chile, Colombia, Costa Rica, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Puerto Rico, Nicaragua, Panama, and Peru. Ceviche is considered the national dish of Peru and is recognized by UNESCO as an expression of Peruvian traditional cuisine and an Intangible Cultural Heritage of Humanity. The fish or shellfish in ceviche is not served raw like sashimi; the citric acid from the citrus marinade causes the proteins in the seafood to become denatured, resulting in the dish appearing to be "cooked" without the application of heat. The fish is typically cured in lemon or sour lime juice, although sour orange was historically used. The dressing also includes some local variety of chili pepper or ...

Sour Mash
Sour mash (or sourmash) is a process used in the distilling industry that uses material from an older batch of mash to adjust the acidity of a new mash. The term can also be used as the name of the type of mash used in such a process, and a bourbon made using this process can be referred to as a ''sour mash bourbon''. Sour beer may also be created with this process. Well-known brands of sour mash whiskey are Jim Beam and Jack Daniel's. Process In the sour mash process, the mash – a mixture of grain, malt and water – is conditioned with some amount of spent mash (previously fermented mash that still contains dead yeast, a good food source for live yeast). Spent mash is also known as spent beer, distillers' spent grain, and slop or feed mash because it is also used as animal feed. The acid introduced by the sour mash controls the growth of bacteria that could taint the Bourbon. An established and active strain of live yeast is introduced into the mash to be f ...
