What is kosher food?
Kosher food is food that is prepared in accordance with Jewish dietary law. This includes not only what foods are permitted to be eaten, but also how those foods are prepared and which utensils are used to eat them.
For example, kosher law requires that meat and dairy products be kept separate, so a kosher kitchen will have two separate sets of dishes and utensils. Kosher law also has strict rules about which animals can be eaten and how they must be slaughtered.
