A steamer can also be used to reheat tamales. A dozen tamales should be steamed for 20 to 30 minutes on medium heat.
Tamales can be reheated in an oven set to 425 degrees Fahrenheit. It is important to first remove the husks before using this heating method. Place tamales in a lightly buttered pan and cook for 30 to 45 minutes or until the skin of the tamale is crispy and golden.Learn more about Cooking
