Mamasita's Tamales are pre-cooked so heat them until they are hot. The best way to heat tamales is to use a steamer for 15 to 20 mins.
Stove top: Steam in covered pan with 1/2" of water for 15 -25 mins or until warm.
Microwave: Wrap in damp paper towel, heat for one to two minutes.
Remove husk before eating.
