Greeks don’t know from a bagel, but on almost every street corner in the center of Athens you’ll find stands selling koulouria, a sesame seed-sprinkled bread stick-slash-roll. Athenians grab them on the go for a quick breakfast in the early morning while they’re fresh. But don’t be turned off if you see some still for sale after lunch – by afternoon the koulouria somehow morphs into a satisfyingly crunchy snack.
