Milk is the first product in the life of every person, because we are representatives of the mammals class. But if the rest of the representatives of the same class, growing up, completely switch to other foods, then a person does not refuse milk until he is old. About what is made from milk, you can talk for hours. The dairy industry occupies a huge market segment.
In order to make sure of this clearly, it is enough to visit any supermarket and evaluate the percentage of dairy products in the windows of the grocery department. The production of milk and dairy products is a very profitable business, since there is practically no waste from it. Everything goes into business and absolutely everything is in demand by the consumer.
Let's see what is made from milk and where dairy products diverge. Here the milkmaid received fresh milk from a cow . This is a completely ready-to-use product. You can just drink it, or you can, after having undergone some transformations, get many other products from it. Fresh milk itself is drunk by a relatively small percentage of the population, since it is a very “perishable” product. It stood a little and ceased to be a pair, so that only those who have access to milk producers, in other words, to cows, can enjoy it. It is clear that we are talking only about residents of the countryside, since it is impossible to keep a cow in a city apartment. Although, according to popular rumor, such attempts were made.
But back to what is made from milk. It stood up for us and ceased to be paired. To accelerate this process, it is forcibly cooled, placed in a cool environment. The villagers, without further ado, simply put milk in the glacier or lowered the can filled in the well. After some time, a dense layer of cream is collected on the surface of the milk, which is the fat that has surfaced on the surface. It is drained (now the origin of the name is clear, and the meaning of the idiom “skim cream” becomes clear), and skim milk remains in the container - reverse.
You can just drink cream, or you can put it in a cold place and get sour cream in a few days. In order to speed up this process, leaven is introduced into skimmed cream - in the villages a little sour cream left over from the previous time is used as sourdough. After you dare the resulting product (yes, it was from this verb that your name was sour cream), you still have serum.
Along with what is made from milk, one cannot miss two such popular products as cottage cheese and cheese. The processes of their preparation are basically similar, only the cottage cheese is ready in a day, and the cheese must ripen, and very specific conditions are necessary for its ripening. By the way, after the curdled mass has been removed from milk, again there is serum that can either be drunk just like that, or added to okroshka, or used for baking.
It was all about fresh milk, but what if the product went bad due to heat and lack of time, that is, sour? Any experienced hostess will tell you that a lot of very, very tasty dishes can be made from sour milk. Yes, the same kefir, yogurt and fermented baked milk, tan, ayran, etc. - No wonder that they relate to a number of dairy products. By the way, glue was even made from milk, so there is an application for everything in dairy production.
