Heat oil on high in a large skillet. Cook onion and garlic for 2 to 3 minutes until softened. Add lamb and cook, breaking it up as you go, until mostly browned. Then add all the spices (cumin, coriander, cinnamon, paprika, allspice, cayenne, black pepper, and salt) and cook for 1 minute.

Open the filo pastry packet and unroll the pastry. Peel one layer off and place on a piece of baking paper. Cover the remainder with a lightweight damp tea towel to prevent drying. Drizzle yogurt wash across filo using a pastry brush, creating a thin layer. Top with another filo sheet, and brush with yogurt wash. Repeat to create 4 layers total, but do not brush the last (4th) layer with yogurt wash.

Place 1/3 of the lamb filling along the bottom edge of the layered filo. Using a long kitchen knife to get started, roll up into a log. The roll should be loose as the pastry is delicate. Repeat to make 3 logs, using all the filling.

Take one log and place on a piece of baking paper. Coil into a spiral. Join a second log to the first by stuffing the ends inside each other, using yogurt wash to adhere. Continue forming the spiral with the third log. Log sides should be in contact but not tightly squished.
