HOW LONG ARE FROZEN TAMALES GOOD FOR 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:

• Place chicken (or turkey), 1 onion wedge and whole garlic clove in a medium saucepan and cover with cold water. Bring to a boil over high heat. Reduce heat to a low simmer, cover and cook until an instant-read thermometer inserted in the thickest part registers 165°F, about 12 minutes. Transfer the meat to a clean cutting board to cool. Shred the meat.
• Meanwhile, soak cornhusks in a large pot or bowl of hot water. Weigh the husks down so they stay submerged.
• Chop the remaining onion wedge. Heat 1 tablespoon oil in a medium saucepan over medium heat. Add the chopped onion; cook, stirring occasionally, until translucent, 2 to 3 minutes. Add minced garlic; cook, stirring constantly, until aromatic, about 30 seconds. Add tomatoes and cook, stirring, until they soften into a thick, chunky paste, 3 to 5 minutes. Stir in the shredded meat, chipotles, adobo sauce, oregano, pepper and 1/2 cup broth. Stir in 1/4 teaspoon salt and bring to a boil. Lower the heat, cover and cook for 5 minutes. Transfer to a bowl and set aside.
• If using fresh masa, put it in a large bowl and add 1/2 cup broth. Knead with your hands until a wet dough forms. (If using masa harina, place it in a large bowl and add 2 1/4 cups broth. Mix until evenly moist and soft.)
• Pour the remaining 1 1/4 cups oil into the bowl of a stand mixer fitted with the paddle attachment. Add the dough, 1 tablespoon at a time, to the oil while mixing on low speed and working up to medium speed once the dough comes together.
• Add baking powder and the remaining 2 teaspoons salt. (If using masa harina, add an additional 1/2 to 3/4 cup broth if the dough seems stiff.) Mix on high speed for 10 minutes, scraping down the sides as needed, until the dough is smooth and fluffy.
• To assemble tamales: Remove a husk from the water and pat dry. Choose the largest, thickest husks that don't have any holes. Peel off and discard any dried corn silk.
• Use a rubber spatula to spread about 1/2 cup of dough (or less: the amount will depend on the size of your husk) in a rectangle on the husk, leaving about 3 inches of space on the narrower end of the husk, where you'll fold it closed, and 2 inches of space on the other end. Using a slotted spoon, add about 1 tablespoon of the reserved filling down the middle of the dough. Bring one end of the husk toward the other and press together lightly to seal the dough inside the husk. (If the filling spills out, you've added too much, but you can spoon a little more masa on top of any leaks.) Tuck the edges of the husk under each other to form a long tube. Hold the tube vertically and press firmly on the bottom edge of the tamale to seal. Fold the husk back in the place where you've sealed it. Place on a baking sheet and repeat to make the remaining tamales.
• Add 1 inch of water to a large pot fitted with a steamer basket. Line the basket with a layer of husks. Bring the water to a light boil. Add the tamales carefully in a vertical position. Steam, adding more water if necessary, until the husk just starts to pull away from the dough, 35 to 40 minutes.
• Using tongs, transfer the tamales to a baking sheet; let cool for 15 minutes. Serve the tamales with salsa, crema (or sour cream) and avocado, if desired.
