Ingredients:
- 1 kg ground beef (80/20 lean-to-fat ratio)
- 2 large yellow onions (grated and squeezed dry)
- 2 tbsp ground sumac
- 1 tsp ground turmeric
- 2 tsp kosher salt
- 1 tsp cracked black pepper
- 1/2 tsp saffron threads
- 2 tbsp hot water
- 50g unsalted butter
Instructions:
- Grate the yellow onions into a fine pulp using a box grater or food processor. Place the pulp in a fine-mesh strainer or cheesecloth and press aggressively to remove all excess liquid until only a dry pulp remains.
- In a large chilled mixing bowl, combine the cold ground beef, dried onion pulp, sumac, turmeric, salt, and black pepper.
- Knead the meat mixture vigorously for 10 minutes. This develops myosin proteins, creating a 'cold emulsion' that helps the meat bind to the skewer. The meat should become pale and tacky.
- Cover the bowl and refrigerate the meat mixture for at least 1 hour to firm up the fats.
- Bloom the saffron threads in 2 tablespoons of hot water, then stir in the melted butter to create the basting glaze.
- Divide the meat into 8-10 equal balls. Mold each ball onto a wide, flat stainless steel skewer (Varesh), using wet hands to create the signature indentations along the length of the meat.
- Grill over high heat charcoal (Mangal) or under a high-heat broiler for 8-10 minutes, flipping every minute. Baste frequently with the saffron butter glaze during the last 2 minutes until a mahogany crust forms.
