Seventy-six year-old grandmother and math teacher Ruth Teig teaches Mo Rocca how to make classic Jewish cuisine. On the menu is kreplach (or Jewish ravioli) and Ruth's fluffy, modernized version of gefilte fish. Ruth surprises Mo with a large live Carp in her bathtub to teach him how generations of Jews in Europe would keep their fish fresh before the invention of refrigeration. Mo also gets to taste Ruth's magical coffee cake that she uses as currency to feed household workmen and to allows her to skip to the front of long lines at the DMV.
