Combine ginger, garlic, 4 Tbsp of the lemon juice, honey, chili powder, cornstarch, salt and pepper and melted butter in a blender and blend well to make a smooth paste
You may need to add some water or a little more lemon juice to make the paste a little runny
Stab chicken breasts all over with the point of a sharp knife
Rub the spice paste over the chicken and allow to marinate for at least 45 minutes (longer for a stronger flavor)
Notes
Roast chicken breasts on a rack across a roasting pan at 400 degrees for 45 minutes or until meat is cooked through Sprinkle chicken with the remaining 2 Tbsp of lemon juice and coriander and serve over Cashew Rice (recipe follows)
