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.
List of halal and kosher fish
In Judaism, in addition to requiring the presence of true fish scales, kosher fish must also have fins. This seemingly redundant requirement serves to remove ambiguity by excluding finless sea creatures that possess various features which might be confused for scales, including shells (such as those of shrimp or prawns). While not every fish that has fins will have scales, every true fish that has true fish scales by default also has fins. As per the modern scientific definition, in Judaism also, the shells of crustaceans are their exoskeleton ("outer skeleton"), and they are thus not kosher for not only lacking fins but also for lacking true scales.
