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.
Food and drink prohibitions
Certain species of fish are also forbidden in Judaism such as the freshwater eel (Anguillidae) and all species of catfish. Although they live in water, they appear to have no scales (except under a microscope) (see Leviticus 11:10-13). Sunni Muslim laws are more flexible in this. Catfish and shark are generally seen as halal as they are special types of fish. Eel is generally considered permissible in the four Sunni "madh'hab." The Ja'fari jurisprudence followed by most Shia Muslims forbid all species of fish that does not have scales, it also forbid all shell fish species except prawns.
