What Does Kosher Mean?
The term kosher does not refer exclusively to ritually edible foods. Kosher refers to anything that meets Jewish legal requirements. But kosher is most commonly encountered in regard to food. There are many reasons why food can be considered non-kosher. If milk and meat are mixed at the same meal, this is non-kosher. If an animal is not properly slaughtered, this is non-kosher. Food cooked on the Sabbath is non-kosher. Leavened product not disposed of before Passover is non-kosher. The most commonly known non-kosher product is pork.
