African cuisine
Tihlo, prepared from roasted barley flour, is very popular in Amhara, Agame, and Awlaelo (Tigray). Traditional Ethiopian cuisine employs no pork or shellfish of any kind, as they are forbidden in the Jewish and Ethiopian Orthodox Christian faiths. It is also very common to eat from the same dish in the center of the table with a group of people.
Jewish cuisine
Gefilte fish (from German "gefüllte" "stuffed" fish) was traditionally made by skinning the fish steaks, usually German carp, de-boning the flesh, mincing it and mixing with finely chopped browned onions (3:1), eggs, salt, pepper, and vegetable oil. The fish skin and head were then stuffed with the mixture and poached. The religious reason for a boneless fish dish for the Sabbath is the prohibition of separating bones from food while eating [the prohibition of 'borer', separating]
A more common commercially packaged product found today is the "Polish" gefilte fish patties or balls, similar to quenelles, where sugar is added to the broth, resulting in a slightly sweet taste. Strictly speaking they are the fish filling, rather than the complete filled fish. This method of serving evolved from the tradition of removing the stuffing from the skin, rather than portioning the entire fish into slices before serving.
