Diastatic malt powder is the "secret ingredient" savvy bread bakers use to promote a strong rise, great texture, and lovely brown crust. Especially useful when flour does not have barley malt added, as is true for most whole wheat flour and many organic flours.
Active enzymes in diastatic malt help yeast grow fully and efficiently throughout the fermentation period, yielding a good, strong rise and great oven-spring. Add only a small amount, ½ to 1 teaspoon per 3 cups of flour.
