Accompaniments: mango and red pepper chutney and mint raita
Garnish: lime wedges
Directions
Purée all ingredients except chicken in a blender until spices are well ground.
Put chicken in a large bowl, or divide between 2 large sealable plastic bags, and add yogurt mixture, stirring or turning to coat. Marinate chicken, covered and chilled (turning occasionally if using bags), at least 4 hours.
Soak skewers in water 30 minutes. While skewers are soaking, bring chicken to room temperature.
Preheat broiler and brush a broiler pan lightly with oil.
Divide chicken among skewers (about 5 cubes per skewer), leaving an 1/8-inch space between cubes, and arrange about 5 skewers across pan. Broil chicken about 4 inches from heat, turning over once, until browned in spots and just cooked through, 9 to 12 minutes total.
Transfer cooked skewers to a large platter and, if desired, cover loosely with foil to keep warm. Broil remaining chicken in same manner. Remove chicken from skewers and serve warm or at room temperature.
