Prepare your ingredients. For the first filling, mix the tahini and honey well—it will thicken, but don't worry. In a separate small bowl, prepare the second filling by mixing the cinnamon, sugar, and walnuts together.

In a second, larger bowl, mix the flours, mahlab, and salt. Add the activated yeast, olive oil, the remaining water, and vinegar. Knead until you have a smooth, elastic dough that doesn't stick to the sides of the bowl.

On a floured surface, roll each piece of dough with a rolling pin into a very thin, long rectangle (about 20 x 8 inches or 50 x 20 cm).

Spread 1–2 tablespoons of the tahini-honey mixture in a thin line along the length of the dough. Then sprinkle the cinnamon-sugar-walnut mixture evenly over the surface to be rolled.

Roll up the dough (not too tightly) into a thick, long rope.

Twist the rope into a spiral shape. Lightly sprinkle with water and dust with cinnamon on top.
