How to make sour cream at home
Sour cream can be made at home. To do this, add a special sourdough or good quality sour cream to the cream and let it stand at room temperature. When the cream turns sour, it must be put in the cold and kept at a temperature of 5-8 ° C for 24-28 hours, after which the sour cream is ready.
You can make sour cream at home and without "ripening". To do this, add citric acid and an agar or gelatin solution to the chilled cream. The cream will thicken, become sour in taste and, after cooling, will look and taste like sour cream.

Sour cream is so named because it is swept away - as opposed to cream that is drained. This is a primordially Russian national product, familiar for a long time only to the inhabitants of our country. It penetrated abroad only after the Second World War. In some countries, sour cream is called 'Russian cream'.
Sour cream is a spontaneous product. Our ancestors made it simply: they put sour milk and then removed the sour cream from above. The milk was defended for several days. It was believed that the longer the milk is allowed to settle, the more sour cream will form on top.
Now sour cream is made from cream, which, according to the standards, must have a 32% fat content.This fat content of the cream is provided taking into account the introduction of a 5% bacterial starter culture prepared on skim milk. The starter culture includes pure bacterial cultures: lactic acid and creamy streptococci, as well as aromatizing bacteria.
Sour cream is produced in different fat contents: from 10% (dietary) to 20, 25, 30, 36 and 40% (amateur). It is widely used in natural nutrition, in cooking. At home, when used for culinary purposes, it is whipped better if you add a little raw egg white to it. Sour cream improves the nutritional value and taste of various dishes, especially gravies, sauces, seasonings. It is also used in medical nutrition. Its digestibility is better than cream. This is due to certain changes in milk proteins during fermentation. This is why doctors recommend sour cream for people with poor appetite and poor digestion.
Sour cream is a high-calorie product containing a high percentage of fat. This must be borne in mind by those who have a weakness for her and are able to eat a lot. A good sour cream should be thick, fat, without grains and not very sour. Real genuine sour cream is made from cream alone, in contrast to the sour cream that is often found on sale and contains a lot of cottage cheese. Such sour cream, although thick, but not greasy, does not disperse well in cabbage soup, contains small lumps that are felt on the tongue. Finally, such sour cream is not suitable for some purposes, for example, for churning, making cakes, etc.
The rules and conditions for making sour cream are the same as for yogurt. Sour cream is prepared either with samokvass, or with the help of sourdough, which is either old sour cream or yogurt. The usual method of making sour cream, practiced everywhere in villages and estates, is as follows. Pots of milk are taken out to the sludge and kept until the settled cream turns sour and forms sour cream. It must be added that for sour cream, the pots must be kept in a place warmer than those pots in which the milk is settled. It is even better to keep it right in the kitchen (and in winter it is necessary), and when the cream has soured, put it out in the cold. A day later, when the sour cream has grown stronger, it is removed from the top, and at the bottom there is a skinny yogurt, which is used to boil cottage cheese. This method is the simplest, but inconvenient for making sour cream in large quantities and more or less homogeneous. It is much more convenient to prepare sour cream from cream previously removed from milk.
The cream for sour cream can be skimmed either in the usual way, or on the separator. But the methods of making sour cream from this or that cream are different. This difference is that the cream obtained by settling can be used to make sour cream immediately after it has been removed. Cream from the separator must not be immediately put into operation. They need to be kept in the cold for some time. If you want the sour cream to sour more quickly, you can preheat the cream to 25-30 degrees; such sour cream is more likely to form, but it will be slightly sour than the first. Some, wanting to get a smoother sour cream, have the habit of stirring the cream from time to time with a spatula until they begin to thicken, then only they are left alone and taken out into the cold. But this method cannot be particularly recommended. First, because any movement, any jolts interfere with the correct souring of the cream and release a part of the whey; secondly, the mold and, in general, the fermenting principles that collect on the surface of the sour cream, thus, will be introduced into the mass of the sour cream, which makes it less durable and of high quality. When the sour cream is finally ripe, then only you can interfere.
When buying sour cream in stores or on the market, remember:
- if the shelf life of sour cream is increased or it contains components of non-dairy origin, then this product is not sour cream !;
- good sour cream should have an even, thick consistency and a high content of milk fat;
- if there are lumps in the diluted sour cream, it means that she was 'married' with cottage cheese, previously diluted with kefir;
- low fat sour cream is suitable only for dressing salads or soups, but it is not suitable for cooking hot dishes, such as julienne. The high temperature curdles the low-fat sour cream, releasing whey.

🔗Sour cream preparation
Method 1. Take cream of 25-30% fat content, heat to 60-63 ° C and keep at this temperature for 30 minutes. Then cool, stirring constantly, to room temperature, add the leaven and leave to ferment. In the first 3 hours, the cream is stirred 2-3 times. The end of fermentation is determined by acidity. The fermented sour cream is placed in the cellar for a day at a temperature of 5-8 ° C, stirring occasionally.
Store sour cream can be used as a starter culture. It should be taken about 5% of the volume of the prepared sour cream (this is about 2 tablespoons of sour cream per 1 liter of cream).
For example, in this way you can prepare "Amateur", "Peasant", "Acedophilic" sour cream, etc.
Method 2. In an open jar with cream, add the previously purchased sour cream at the rate of 5% by volume, mix thoroughly and leave in a warm place at room temperature for 8-12 hours (usually overnight). The resulting product is placed for a day in a refrigerator for maturation. The density depends on the fat content of the cream: the fatter the cream, the thicker the sour cream.
If there is no sourdough, then you can use a slice of black bread with a crust, which is taken out before placing the sour cream in the refrigerator.
It is better to store sour cream in glassware for no more than 3 days in a dark place at a temperature of 0-7 ° C.
