The word "kosher", the meaning of which is not known to everyone, means "suitable, acceptable." This concept mainly refers to food. However, with a more detailed study of Jewish culture, it becomes obvious that the meaning of the word "kosher" can be used to characterize human behavior, describe its appearance, and so on.
If you can talk about an object that it is acceptable, permissible and permitted, then it is kosher. The meaning of a word that includes these concepts is multifaceted. But in general, it means the extent to which the object in question is suitable for use at a given time.
For example, beer is a kosher drink for Jews. However, it loses this concept during the ritual of lighting (kiddush). So is bread. It is kosher for everyday food and for kiddush, but loses this definition during Passover, when it is strictly forbidden to eat leaven. At this point, the bread becomes unsuitable for consumption.
The kosher food that a Jew should eat is described in the Torah. This scripture provides a detailed reference to existing species of animals whose meat can be eaten. As for the plants, the conclusion suggests itself - they are all kosher.
The Torah divides all animals into four species. These include "fish, poultry, meat and other rubbish" (insects and reptiles).
Kosher food consisting of fish dishes should be prepared with certain seafood. They must simultaneously include three components. Used fish must have scales, gills and fins before cooking.
In the Torah you can find a list of birds whose meat may be present on the Jewish table. Basically these are those species that can not eat carrion. Thus, kosher food can be prepared from the meat of ducks and chicken, turkeys and geese. Unacceptable to Jews, for example, ostrich meat. In accordance with this, the use of eggs of these birds is also unacceptable.
Kosher on the Torah is ruminant meat, and even then only those with all four hooves bifurcated. Thus, during the Jewish meal, you can see dishes prepared from lamb and goat meat. Torah is allowed to eat cow meat. Pigs, rabbits, horses, hares, etc. Jews are considered non-kosher.
All other living creatures, except for four species of locusts, are also unacceptable for food. Consequently, Jews should not eat crabs, crayfish, snakes, snails, etc.
It should be borne in mind that the Torah also considers prohibited those products that originated from non-kosher animals (caviar, milk, fat, etc.).
Kosher food must be prepared using permitted methods. The basic law of scripture prohibits the use of blood in any form. That is why the meat is thoroughly soaked in salt water before cooking. If bloody spots are found in raw eggs, then the whole egg is thrown. The meat used by Jews for food should only come from animals or birds that have been properly slaughtered. The permitted method of killing is considered to be instant cutting of the esophagus, artery and respiratory tract. The animal does not feel pain and does not experience the fear of death.
All kosher products are of high quality. The culinary traditions of the Jewish people are considered the most stringent in the world. Before entering the trading network, kosher products undergo mandatory control.
