The straight mixing method is most often used with formulas that rely on direct fermentation. For this mixing method, the ingredients are added in a different order depending on the type of yeast used. If instant dry yeast is used, the yeast should first be blended with the flour, then combined with the remaining ingredients. If active dry or compressed fresh yeast is used, the yeast should first be blended with the water and allowed to fully dissolve. Next the flour should be added, and all remaining ingredients should be placed on top of the flour.
