The title just about says it all. A White woman Serves a dish to her daughters new in-laws. She serves something with meat in it. While they are eating she admits she added cream to the recipe, not knowing that this would be a problem. The Jewish Mother in law is very distraught to find out it wasn’t kosher. That’s all I remember. It’s driving me crazy
I remember an episode of Seventh Heaven where the eldest son is going to marry a Jewish girl, so they have a big dinner with both families, and this happened. The bride-to-be’s mom is so upset about the broken kosher law that she leaves the table.
(I just looked it up – that episode is called Lip Service)
