Combine beans with all dry ingredients (add red pepper flakes to taste, a little goes a long way) and soy sauce in a large bowl.
Mix with your hands to ensure even distribution.
Add water and then knead dough about 10 times and set aside. Grab 5 rectangular shapes of foil and prepare your steamer (turn it on and get it ready). Divide dough into 5 equal parts and, using your hands, shape it into a log on the tin foil. Wrap each piece tightly in tin foil, twisting the ends to close. Steam for 40 minutes.Nutritional Information
