A rich, deeply spiced curry slow-cooked until the aromatic tomato and onion reduction clings intimately to the tender cuts.
Coat the lamb cubes with lemon juice and salt, then mix in the yogurt, ginger-garlic paste, chili powder, cumin, and garam masala, and rest for 2 hours.
Thread the marinated cubes onto skewers, leaving small gaps between pieces.
Grill over charcoal, turning regularly, for 12-15 minutes until charred outside and juicy within.
Brush with mustard oil halfway through cooking.
Slide the boti kebabs off the skewers and serve hot with onion rings and mint chutney.
