16 ounces ground lamb
2.5 teaspoons kosher salt
1 teaspoons ground black pepper

2 tablespoons hot water
2 tablespoons unsalted butter β melted

Instructions
Line a bowl with a clean kitchen towel or several layers of cheesecloth. Add the onion, then wring firmly to expel as much liquid as possible until the pulp is very dry.
In a large bowl, combine the ground beef, ground lamb, drained onion pulp, kosher salt, ground black pepper, and ground turmeric. Knead vigorously with your hand until the mixture turns sticky and paste-like, 5β7 minutes.
Cover and refrigerate the mixture to firm up, 1β2 hours.
In a small bowl, stir together the saffron threads and hot water; let bloom 5 minutes. Whisk in the unsalted butter to make a saffron-butter baste and set aside at room temperature.
Prepare wide, flat metal skewers. With slightly damp hands, divide the chilled meat into 8 equal portions. Press each portion onto a skewer in a 8β9 inch strip about 0.5 inch thick, pinching along the length to form shallow ridges. Lay skewers on a tray and refrigerate 15β20 minutes while you heat the grill.
Build a hot charcoal fire for direct grilling (or preheat a gas grill on high) and clean the grates well.
Thread the tomatoes onto separate skewers (or use a grill basket) and set aside near the grill.
Place the meat skewers over high direct heat. After 2 minutes, when the underside is set and releases cleanly, flip. Continue grilling 6β8 minutes total, turning every 1β2 minutes and brushing with the saffron-butter baste during the last few turns, until the kebabs are well browned with light char and cooked through.
Grill the tomato skewers alongside until blistered and softened, 8β12 minutes, turning occasionally.
Slide the kebabs off the skewers onto lavash, sprinkle with sumac, and serve hot with the grilled tomatoes.
