Mix 3 tablespoons natural peanut butter with a cup of lukewarm water, just enough to obtain a liquid solution, and pour into the water.
Mix 3 tablespoons flour (wheat, corn or millet) with lukewarm water in order to dissolve it thoroughly also into a liquid solution, and pour the liquid into the boiling mixture.
Add curdled milk (roaba) or if you lack some, add lemon juice until a sour taste and white brightness is obtained.
