Soya flour can be used as-is, or, for a pleasant nutty flavour, toast it before adding it to a recipe. Place the soya flour in a dry skillet and stir over medium heat for a few minutes.
Soya flour can be used as a thickening agent in gravies and sauces, or it can be added to baked goods. In baked products, soya adds tenderness and moisture and helps to keep products from becoming stale. Products containing soya flour brown more quickly, so it is sometimes necessary to either shorten the baking time or decrease the temperature slightly. For products that do not contain yeast, such as muffins and cookies, replace up to 1/4 the total amount of flour called for in a recipe with soya flour.
