Multiple eastern Mediterranean countries and communities (Israel, Lebanon, Palestine, Egypt among them) claim hummus as a national dish, but the documentary record does not fix a single point of origin; the earliest known written recipes are 13th-century Syrian and 14th-century Cairene.
What would resolve this A written recipe or reliable archaeological attestation predating the 13th-century Syrian and 14th-century Cairene cookbook records, tied unambiguously to one people or place, would settle the question; none has yet been found.
