1. Cut dough into five or six parts. Roll out each piece into a round disc about a quarter-inch thick. Smear with apricot jam. Sprinkle walnut and sugar mixture on top
2. Cut dough into 12 to 16 triangles, like you would a pizza. Roll each triangle up from the wider end. Combine water and egg yolk for egg wash and brush over dough. Repeat for each of the balls of dough.
3. Bake for 18–20 minutes, until golden.
