Soya flour is extremely rich in protein, so it can be added to any food to enhance its nutritional content. It is often used in commercial products such as crisps and sausages. For the home cook, it is valuable for baking, making flatbreads, and thickening sauces. It is often combined with wheat or other grain flours before use. The Japanese use soya flour to coat sticky rice pastes, and the Vietnamese combine it with soya milk and honey to make pancakes.
