Meat and milk

The Torah is especially strict about foods that are a mixture of meat and milk. Not only is it forbidden to eat them, but it is also forbidden to cook and even derive any benefit from them - for example, to sell or feed them to an animal.
If such a mixture was formed by chance, and milk and meat have approximately equal or similar volumes, then the food itself must be destroyed, and the dishes in which it was prepared must be cleaned - "kasher". Until this is done, the use of this utensil is prohibited.
If there is much less milk in this mixture than meat, or. on the contrary, there is much less meat than dairy, it is necessary to seek the advice of a rabbi (since, perhaps, this food still remained permissible).

In order to minimize the likelihood of a mixture of milk and meat, in Jewish homes there should be two complete sets of dishes, spoons, forks, knives and all kitchen utensils, up to coasters for hot pots and washcloths for washing dishes: some of them are used only for dairy food, others - only for meat.
REMEMBER: after eating meat food, you must wait 6 hours to eat milk; after eating dairy food, rinse your mouth and wait only half an hour (an exception is hard cheese such as Dutch: after it, they also wait 6 hours to eat meat).
