Sauté the filling
15 minFinely chop the onion and sauté it in vegetable oil until softened. Add the ground beef and sauté for 9 more minutes, until it releases and reabsorbs its juices. The filling is ready when no liquid runs to the bottom as you tilt the pan; a watery filling will soak the yufka from the inside. Add the spices after removing the pan from the heat, then spread the filling on a wide plate to cool.
