Non-Frozen tamales:

Stove-Top Steaming:  15-20 Minutes

In a pot or pan, place a small amount of water (about an inch full) and place the tamales in the pan, cover the pan and steam on medium heat

Microwave Steaming:  1-2 Minutes Each

In a plastic bag, with a few tablespoons of water poured into the bag.  If the tamales get wet, it’s okay, because their wrappers protect them.

Large Amounts:  30-40 minutes

Frozen Tamales:

Stove-Top Frozen:   25 Minutes

Microwave Frozen:  3-4 Minutes Each

Note:

It’s important to use steam heat only, stove-top heating is preferable, however you may microwave them by  placing the tamales with their traditional wrappings (corn husks)  still on.

If you do not have a plastic bag handy, wet a paper towel and place the wet paper towel around the tamale and place in the microwave.
