HOW TO REHEAT FROZEN TAMALES IN INSTANT POT RECIPES

Steps:

• Season the pork generously with salt and pepper. Select Sauté on the Instant Pot and warm the oil. In batches, sear the pork until browned on all sides, about 8 minutes total. Using tongs or a slotted spoon, transfer the pork to a plate.
• Add the onions to the pot and cook, stirring occasionally, until tender and translucent, about 3 minutes.
• Stir in the cumin and garlic powder, return the pork to the pot, add the broth and chiles, and give everything a good stir. 
• Lock the lid in place and turn the valve to Sealing. Press the Keep Warm/Cancel button to reset the program, then press the Manual/Pressure Cook button and set the cook time for 1 hour at high pressure. 
• Let the steam release naturally for about 10 minutes, then turn the valve to Venting to release any residual steam.
• Carefully remove the lid and, using a slotted spoon, transfer the pork mixture to a bowl. Using 2 forks, shred the pork.
• Add the cilantro, season with salt and pepper, stir well and let cool to room temperature. Using pot holders, lift out the inner pot, rinse well, and return the inner pot to the Instant Pot housing.
• In a large bowl, mix the corn masa mix, salt, and baking powder, then stir in 3 cups of the water until blended.
• Stir in the vegetable shortening, then knead the masa against the side of the bowl until incorporated. 
• Remove the husks from the water and pat dry. Place the husks on a work surface with the narrow ends facing you.
• One at a time, spread about 3 tablespoons of the masa mixture onto the widest part of a husk and top the masa with about 1 tablespoon of the pork mixture. Fold in the sides of the husk to enclose the filling, then fold up the bottom narrow flap of husk over the center and secure with a narrow strip of the husk. Repeat until all the filling is used.  
• Pour the remaining 1 cup water into the Instant Pot and insert the steam rack. 
• Arrange the tamales on the rack, standing them upright. Lock the lid in place and turn the valve to Sealing.
• Press the Manual/Pressure Cook button and set the cook time for 40 minutes at high pressure.  Let the steam release naturally for about 10 minutes, then turn the valve to Venting to release any residual steam.
• Carefully remove the lid and transfer the tamales to a plate. Let stand for 15–30 minutes to set up before serving.

Steps:

• Soak the corn husks. Place 1 package corn husks in a large pot or bowl and add enough hot tap water to cover. Make sure the husks are submerged by weighing them down with a few coffee mugs.
• Cook the pork. Cut 1 pound pork shoulder into 2-inch chunks. Season with kosher salt and black pepper. Place in a large saucepan. Cut 1/2 large white onion into 2 pieces, and add 1 piece to the pan. Add 1 of the garlic cloves, 1 bay leaf, and 2 1/2 cups water. Bring to a simmer over high heat, about 7 minutes. Reduce the heat to low, cover, and cook until the pork is fork tender and falling apart, stirring every 20 minutes to prevent the bottom of the pot from burning, 1 to 1 1/2 hours total. Meanwhile, start the chile sauce.
• Cook the chile sauce ingredients. Husk and rinse 1 pound tomatillos. Place in a medium saucepan. Add the remaining onion piece, remaining garlic clove, and 4 serrano peppers, and cover with 1 inch of cold water. Bring to a boil, then lower the heat to medium. Simmer, stirring occasionally, until the items have softened, about 8 minutes for the tomatillos and peppers, and 12 minutes for the onion and garlic. Use a slotted spoon to transfer the items to a bowl as they are ready. Let cool slightly, then coarsely chop the peppers (discarding any tough stems), onion, and garlic.
• Cool the meat. When the pork is ready, use a slotted spoon and transfer it to a bowl. Remove 1/4 cup of the broth for the sauce. Let the pork cool slightly, then shred with your fingers or two forks.
• Blend the sauce. Place the tomatillos, chopped chiles, onion, garlic, and 1/4 cup broth in a blender and blend until smooth.
• Combine the sauce and meat. Heat 1 tablespoon canola oil in a medium saucepan over high heat until shimmering. Add the sauce in one quick pour. Stir in the shredded pork. Add 1 tablespoon kosher salt, 1 teaspoon ground cumin, 1 teaspoon Mexican oregano, and 1/2 teaspoon black pepper. Bring to a boil and cook for 3 to 4 minutes to let the flavors meld. The filling should taste salty—it needs to be saltier than you’d think, to stand out inside the tamales. Remove from the heat and set aside.
• Knead the dough. If using masa harina for your dough, place 3 cups masa harina in a deep mixing bowl and pour in 2 1/4 cups chicken broth. Mix with your hands until the dough is moist and soft. If using fresh masa, knead 1/2 cup chicken broth into 2 pounds masa with your hands until a firm dough forms.
• Mix the dough. Pour 1 1/4 cups canola oil into a stand mixer fitted with the paddle attachment. (Alternatively, use an electric hand mixer and large bowl.) With the mixer on low speed — and don’t wear your best clothing, because it will splatter — add the masa in golf-ball-sized pieces one at a time. The dough may look rather lumpy and unattractive here, but it will eventually transform. Stop the mixer and sprinkle in 2 teaspoons kosher salt and 1 1/2 teaspoons baking powder. If using masa harina, stir in an extra 1/2 cup chicken broth. Mix on high speed until the dough is very light and fluffy, about 10 minutes more.
• Spread the dough inside the husks. Remove 1 corn husk from the water and wipe off any extra water with a towel. Use a rubber spatula to spread about 1/4 to 1/2 cup of dough (the amount depends on the size of the corn husk) in a large rectangle. Leave a few inches of space at the top so the dough doesn’t burst out once it’s cooking, and leave about 3 inches of space at the narrower end of the leaf so you have room to fold it.
• Add the homemade filling. Add a small amount of the pork filling (about 2 tablespoons) in a line down the center of the tamal. Don’t add too much, or else it will spill out of the husk when you’re folding it.
• Fold the tamales closed. To close the tamale, bring one side of the tamal toward the other, like an empanada or a taco, and press lightly to seal. Then tuck the leaves of the husk over each other into a tube-shape. Press down on the narrower end to seal, then fold up toward the wider end. Set aside folded side down and repeat with the remaining tamales.
• Steam the tamales for 35 minutes. Add water to a steamer pot and line the insert with a layer of corn husks. (This helps keep the steam trapped inside and adds a bit of flavor.) Bring the water to a light boil. Place the tamales vertically, open-side up in the steamer, but don’t pack them too tightly or they won’t have room to expand. Cover with some extra corn husks. Cover and steam until the corn husk easily pulls away from the tamal, about 35 minutes.
• Let the tamales cool 10 to 15 minutes. Don’t eat the tamales immediately after you remove them from the pot, as they’ll be too soft still. Let the tamales cool for 10 to 15 minutes — they’ll firm up quite a bit and be ready to eat.
