Question 6.1:
What is Kosher? Doesn't a rabbi just bless the food?


Kosher ("fit") food must meet the complex requirements of Jewish law, and the supervising rabbi verifies that such is the case for a given food item, or item which will come in contact with food. There are restrictions on which foods are permitted during different times of the year, and a procedure for slaughtering permissible animals with minimal pain to the animal.

The rabbi's role is to decide questions of Jewish law. In the area of kashrus, there are hundreds of details that must be met, and thousands of "oops, now what?" questions that must be answered. Animals, for example, are killed in a very precise manner, by a "shochet", and they must be checked internally for disease, have their blood removed by salting, feathers removed in cold water, and so on. Kosher wine may not come into gentile contact before pasteurization. Vegetables must be examined for insects. Because meat and dairy have to be carefully separated, precautions against milk-based additives have to taken. The complications can be immense.

A rabbi will hire a mashgioch to do the actual supervision. The latter is supposed to call in the rabbi when a novel situation comes up.

Note that the Reform movement does not mandate observance of the laws of Kashrut. Instead, it advises its members to study the laws of Kashrut and to follow those that the individual feels increases the sanctity of their life and their relationship to G-d. As a result, there are some Reform Jews who do keep kosher. Also, many Jews keep some aspect of the kosher laws, such as not eating pork or shellfish.

Rabbis (and others) sometimes recommend avoiding certain food products based on concerns other than kashruth, for example:

Some rabbis choose not to supervise certain products based on considerations of the above sort.
