Question: how long does it take to cook frozen tamales?
Answer: For steaming, remove tamales from bag, and place in a hot steamer for 15-20 minutes from a thawed state (5-10 minutes more if frozen). For oven baking, preheat oven to 325. Remove tamales from bag, wrap in foil, and place them on sheet pan. Bake 15-20 minutes if thawed, and 20-25 if frozen.
