Of all the products which are available with kosher certification, yogurt is one of the most difficult to locate. Just like milk and cheese, it is a dairy product which means that it is already partially restricted, but while kosher milk and kosher cheese is fairly accessible, it seems as though kosher yogurt options are much more widely restricted. Anyone who wants to use yogurt as part of a recipe, but can't find kosher or even parve yogurt from their local suppliers, needs to understand why it is so hard to make a yogurt while observing the Jewish laws on the ingredients and preparation of kosher foods.
