When ready, grab a large handful of softened corn husk and shake off the excess water. Bring out your masa flavors and set up your assembly station. If you are using any ad ins, like chocolate chips, coconut or raisins, pour them into small bowls at set them nearby.
Pour water into your steamer pot just below where the steamer insert will go. Stay below that line, otherwise too much water could affect the texture of the masa. Place the pot on medium/low heat while you assemble all the tamales.
If the corn husk is extra wide, you could tear it down on one side so it is about 6 inches across. To each corn husk you will add 3-4 tbsps of flavored masa to the center. No need to spread the masa. Mix the flavors or just add one flavor. Add in some of the coconut, chocolate chips or raisins down the center if you like. Press them gently into the masa. Fold in the sides and then fold the flap down. Repeat until you have used all the masa. Depending on how big you prepare the tamales, this recipe yields about 36 medium tamales.
When ready, take some of the extra husks and tear them into strips. Place them at the bottom of the warming steamer pot on top of steamer insert. Turn heat up to high. Take two tamales and hold them together with the flaps on the inside. Place them in the steamer pot this way, open side up. Repeat until pot is full.
Take the remaining corn husk and cover the tamales to keep water out of the top. You can use a clean kitchen towel or some parchment paper on top of the husk to cover even better. Place lid on pot. If needed, place a heavy bowl or your molcajete on top to keep lid on tight. Once the steamer begins to steam rapidly, reduce the heat medium and set your timer for 1 hour. After one hour, carefully pull out one tamal and let it sit for 3 minutes before you try to unwrap it. If the husks pulls away fairly easy, they are ready. If not, steam for another 10 minutes. Remove from the heat and let them sit in the pot to finish setting up.
Store tamales in plastic storage bags once completely cooled. They will last refrigerated for 7-9 days.
