For red or green masa, reduce the amount of chicken broth by 1/2 cup. Replace the 1/2 cup of broth with 1/2 cup red chile sauce or green chile sauce. On occasion I will use a good quality chile ancho or chile guajillo powder to color my masa. The red chile tamales featured on this blog post were prepared with chile powder. Depending on how much color you want to add is how you decide how much to add to the masa. Always have extra broth on hand in case masa appears to be too thick.
