Sprinkle lamb with a mixture of salt, pepper, and cinnamon. In a small saucepan combine crushed pineapple chunks, chopped jalapeño, apricot jelly, lemon juice, prepared mustard, and salt. Bring to a boil, stirring until the jelly is melted.
Meantime, broil lamb 4-inch from the heat, for 11 to 13 minutes. Baste with the sauce during the last 5 minutes of cooking.
