Is a special kitchen required to prepare kosher food?
In fact, two special kitchens are required to prepare kosher food. One kitchen is for the preparation of meat dishes. A second kitchen is required for the preparation of dairy based dishes. Kosher cooking utensils that come into contact with non-kosher ingredients and are then used to prepare a kosher dish, render the finished dish non-kosher. Implements from one kitchen must never be used in the other and cutlery and crockery used for meat dishes must never, ever be used for dairy dishes, and visa versa.
