Hamburgers and ketchup, hot dogs and mustard. Many of us who grew up in the United States learned these food pairings early in life, at ballparks, backyard cookouts and birthday parties. In our case, we encountered falafel and tahini sometime later, probably at the urging of adventuresome schoolmates.

Ahmed Foda – or just “Foda” for short – serves his falafel, too, with the familiar ground-sesame twang of tahini. But at Foda Egyptian Sandwiches, his year-old Astoria food cart, the fritters are called tameya (tah-May-ah) and rely on fava beans rather than chickpeas. This is what distinguishes the Egyptian style of falafel from that of its Levantine neighbors.
