It is believed that Hummus is mentioned in Bible in Ruth 2-14 when
Boaz tells Ruth to come and dip her food into the sauce. The word used
in the Bible is Humutz (Hummus) and similar to the modern Hebrew word
Himtza. It appears from Biblical passages Hummus is mentioned as a
Jewish food long before mentioned as an Arab food.
Hummus is certainly Middle Eastern, and has always been popular in
Syria, Jordan and Egypt. While it's certainly a staple in Israel, it
didn't necessarily originate there. Like many Middle-East foods, it's
virtually impossible to trace its origin as the cultures are ancient,
movement and migration has always been fluid, and the ingredients are
native to the entire region.
Hummus, made from garbanzo beans (a.k.a. chickpeas), is served as an
appetizer, side dish or main course in Israel. Today grocery stores in
Israel sell a variety of Hummus spreads (with pine nuts, with olive oil
and paprika, with zaatar, with tahina...). Hummus tastes best when
scooped up by a piece of warm Pita bread.
