What makes food kosher?
halachah there are three types of food – kosher, non-kosher, and pareve. Kosher food is any food that is determined to be kosher according to halachah (for example: milk, chicken, chocolate). Packaged kosher food is marked by a chesher mark showing that it has been approved by a rabbi as kosher. Unpackaged food is overseen by a rabbi to ensure a kosher standard. Non-kosher food is any food that is determined to be non-kosher according to halachah (for example: pork, cheeseburger). Pareve food is any food that is neither kosher nor non-kosher (for example: nuts, fresh vegetables).
