Despite the name meaning "Laz-style börek" — börek usually being a savory pastry — Laz böreği is entirely sweet, filled with custard rather than cheese or meat.
Thin sheets of dough are layered with a light milk custard, rolled into a spiral or stacked into a tray, and baked until the top turns golden and the inside stays soft and creamy. Trabzon and Rize's pastry shops sell it in wide trays, cut into squares.
