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.
Kosher foods
The Talmud and Yoreh Deah suggest that eating meat and fish together may cause "tzaraath". Strictly Orthodox Jews thus avoid combining the two, while Conservative Jews may or may not.
