I'm just curious what makes food kosher?
Thanks:D

"Kosher foods are those that meet certain criteria of Jewish law. Invalidating characteristics may range from the presence of a mixture of meat and milk, to the use of produce from Israel that has not been tithed properly, or even the use of cooking utensils which had previously been used for non-kosher food. For an in-depth discussion of this tradition, see kashrut."

Kosher foods - Wikipedia, the free encyclopedia

Two things. First certain animals are not kosher (cloven hooves) so any pork product. Second, food must be prepared in such a way as to ensure its not contaminated by anything non kosher.

Generally, a rabbi will inspect the food preparation facility to allow the kosher stamp.

Kosher is the Jewish law for what foods Jews can eat and how they are prepared and how it is eaten.
Fruits and veggies from the garden are Kosher as long as they don't have bugs, (bugs not kosher), Animals that have cloven hooves and chews its could, can be eaten. Animals such as camel, badger, hare, pig not Kosher, the flesh, organs, eggs and likk of these animals are also forbidden. Only fish that has fins and scales can be eaten not shellfish. Grape products made by Non-Jews cannot. All blood must be drained from any meat before it is eaten. Birds and mamals can't be eaten with dairy, and utensils that come in contact with meat cannot be used with dairy. (Just to name a few things!)
