• 1 tspground black pepper
• 2 tspfine sea salt (about 12 g)
• 0.5 tspbaking soda (optional, for extra tenderness)

Instructions

1. 1

   Bloom the saffron by crushing the threads lightly and stirring them into 30 ml hot water. Let it stand for 10 minutes so the liquid turns deeply golden and fragrant.

2. 2

   Make the marinade by mixing yogurt, grated onion with its juices, garlic, lemon juice, olive oil, bloomed saffron, cumin, coriander, paprika, black pepper, salt, and baking soda if using. Whisk until smooth so the spices are evenly distributed and the onion is fully integrated.

3. 3

   Add the sliced lamb to the bowl and massage the marinade into every piece for 1 full minute. Cover and refrigerate for 8 hours so the onion enzymes and yogurt acids tenderize the meat without turning it mushy.

4. 4

   Remove the lamb from the refrigerator 30 minutes before grilling so it cooks evenly. Preheat a charcoal grill to high heat with a strong bed of coals, or preheat a gas grill to 260°C with the lid closed for 10 minutes.

5. 5

   Thread the lamb onto flat metal skewers, folding each slice like a ribbon so it grips the skewer and cooks fast. Leave a small gap between folds to encourage browning, and skewer tomatoes and onion wedges separately so they can be turned at their own pace.

6. 6

   Grill the lamb skewers over direct high heat for 2 minutes on the first side until lightly charred. Flip and grill 2 more minutes, then continue turning every 60 seconds for 6–8 minutes total depending on thickness, brushing with melted butter during the last 2 minutes for a glossy finish.

7. 7

   Grill the tomatoes and onion wedges alongside, turning every 2 minutes until blistered and softened, about 6–8 minutes. Move any pieces that color too quickly to a cooler spot so they soften without burning.

8. 8

   Rest the lamb skewers on a tray for 5 minutes so the juices redistribute and the texture stays tender. Slide the kabob off the skewers and serve immediately with the grilled tomatoes and onions for the classic smoky-sweet contrast.
