Chicken with Spicy Yogurt Sauce

Rinse chicken; pat dry. Lightly score the flesh of the chicken. Place chicken in a large plastic bag set into a shallow dish. In a small mixing bowl stir together yogurt, cilantro or parsley, curry powder, garlic, ginger, paprika, lime or lemon juice, and salt. Pour yogurt mixture over chicken. Seal bag; turn bag to coat chicken with marinade. Marinate in the refrigerator for 2-24 hours, turning bag occasionally. In a large skillet melt the margarine or butter over medium heat. Add the chicken legs and the yogurt mixture. Bring to boiling; reduce heat. Cover and simmer for 45-50 minutes, or till chicken is tender and no pink remains. Transfer chicken to a serving platter. Boil yogurt mixture gently for about 5 minutes, or till slightly thickened. If desired, garnish with cilantro or parsley.
