Step 1

Make the salsa verde, combine it with the shredded chicken, and set aside or refrigerate, if made ahead of time.

Step 2

Place lard, vegetable shortening or seasoned oil in a mixer and beat, until very light, about 1 minute. Add salt and 1 teaspoon cold water, and continue beating until it is white and spongy, a couple more minutes. Add baking powder, and then take turns adding the instant corn masa and the chicken stock. Continue beating until dough is homogeneous and as fluffy as can get.

Step 3

You know the tamal masa is ready if, when you drop 1/2 teaspoon of the masa in a cup of cold water, it floats.

Step 4

Place hot water in the bottom pan of a steamer (only enough so the water is just under the basket with the tamales and not touching them) and bring it to a simmer. Line the steamer basket with one or two layers of soaked corn husks. Use dough to form about 18 cornhusk wrapped tamales.

Step 5

Soak dried corn husks in hot water for a couple minutes, or until they are pliable, and drain. Lay out a corn husk with the tapering end towards you. Spread about 3 tablespoons of masa into about a 2- to 3-inch square, the layer should be about 1/4-inch thick, leaving a border of at least 1/2-inch on the sides. Place 1 tablespoon of filling in the middle of the masa square.

Step 6

Pick up the two long sides of the corn husk and bring them together (you will see how the masa starts to swaddle the filling) and fold the folded sides to one side, rolling them on same direction around tamal. Fold up the empty section of the husk with the tapering end, from the bottom up. This will form a closed bottom and the top will be left open.

Step 7

Prepare all the tamales and place them as vertically as you can in a container. When you have them all ready, place them again, as vertically as you can on the prepared steamer, with the open end on top. If there is space left in the steamer, tuck in some corn husks, so the tamales won’t dance around. Cover with more corn husks, and steam covered for 50 minutes to an hour. You know the tamales are ready when they come easily free from the husks. They will still be moist, and as they are released from the husks, you will see the moistness, like when you remove good moist muffins from their paper baking cups.

Step 8

Finished tamales will stay warm for about 1 to 2 hours in the steamer. They can be made ahead several days before and stored in refrigerator, well wrapped. They can also be frozen for months. In either case, reheat in a steamer. For refrigerated tamales, it will take about 15 minutes, and for frozen tamales about 45 minutes.
