In a medium bowl, combine the yogurt, lemon juice, garlic, cumin, turmeric, salt, and pepper. Add cubed lamb and toss well to coat. Refrigerate for 4 hours, or overnight.
Preheat grill to medium-high. Thread the marinated lamb onto skewers and grill until lamb is cooked through, but still slightly pink in the center. These can also be broiled in the oven. Serve with a drizzle of Maazah chutney (plus a bowl for dipping), over rice, or with warm naan bread.
