2. Adjust for consistency. Keep in mind that once you add in protein powder, the thickness and viscosity will increase exponentially. If you want it thick and pie-like, almost custardy, add only a small amount of extra water or milk. If you'd like to be able to drink it, make it quite watery.
3. Remove from heat, and sift in protein powder.
Note: I found that if one scoops the protein in by the spoonful or single scoop, it clumps and sticks. But sifting lets you stir it and mix it consistently.
