When your tamales arrive, if they are not frozen, they can be refrozen or refrigerated. In the vacuum-sealed bags, they can stay in the freezer 12+ months and in the refrigerator for 3 weeks.
Here are instructions for re-heating them:
• 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.
• For microwave, cut a hole in the bag. From thawed state, heat one bag at full power 3-4 minutes. If frozen, heat at 50% power 3 minutes; turn the bag over, then heat at full power for 1-2 minutes more.
• You may be able to boil the tamales in the bag. However, we cannot recommend this method because dry ice may thin the bag in transit, and when placed in boiling water, it can leak and fill with water. If you choose to boil in the bag, we cannot be responsible for leaks. If you boil in the bag, you’ll have to watch the bag to make sure it doesn’t leak.
