Chicken Mole Tamales (Tamales de Pollo en Mole)

Make the Batter:

1. Whip the shortening in a medium bowl with a hand mixer at medium speed until light and glossy, about 5 minutes.
2. Combine the masa harina, baking powder, and salt in a large bowl. Pour the remaining 2½ cups of broth into the masa harina mixture and beat with the hand mixer at low speed. Raise the speed to high and mix in the shortening one spoonful at a time. Continue to mix at high speed until the batter is very light and fluffy, about 10 minutes. Cover and set aside for 30 minutes.
