We demonstrate multi-grain doughs every chance we get. A good way to make a multi-grain dough is to use your regular dough formula, and just replace 25% (1/4) of the white flour with a commercial, multi-grain blend, available from any commercial, bakery ingredients supplier. Based on the weight of multi-grain mix used, you will need to add 10% additional water to the dough. So, if you added 5-pounds of multi-grain mix to your dough, you would add 8-ounces (10% of 5-pounds) of additional water to the dough. It might feel a bit tacky after mixing, that’s normal, and it will go away as the dough ferments in the cooler. The dough will keep for two days in the cooler. Tip; Since there isn’t any gluten (to speak of) in the multi-grain mix, increase your dough scaling weights by 20% when making these multi-grain crusts.
