Binding Agents

Pure starch; use like arrowroot or tapioca as a thickener or blend component. Not a stand-alone baking flour. Good binding properties reduce egg requirements in some recipes.

When to Choose Water Chestnut Flour

Pure starches are blend components, not primary flours. On their own, starches produce dense, gluey, or gummy results. They need a base grain flour (rice, sorghum, oat) to provide structure and flavor. In a well-formulated gluten-free blend, starch content typically runs 20–40% of total flour weight.

Role in blends: Starches contribute lightness (offsetting the density of grain flours), tenderness, and browning. Higher starch percentage = lighter, more tender crumb. Lower = more structure and chew.

As a thickener: Water Chestnut Flour is effective for thickening sauces, soups, and puddings. It is flavorless, which makes it preferable to wheat flour as a thickener in recipes where you want a neutral flavor. Use about 1 tablespoon per cup of liquid for a medium-thick sauce.
