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 4 weeks.
Here are instructions for re-heating them:
The best way is to boil them in their "boil-in" bag (unless there appears to be extra air in the bag, then the bag may leak, and you should try one of the methods below).
- Place them in the boiling water for 17 minutes from a refrigerated/thawed state (22 minutes if frozen).
- 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, turning the bag. If frozen, heat at 50% power 3 minutes; turn the bag over, then heat at full power for 1-2 minutes more.
