β Tapioca Starch (Best Vegan Option)
1:1 (use equal amount as arrowroot powder)Tapioca starch is a fine, neutral-tasting starch extracted from cassava root, which behaves similarly to arrowroot in baking by providing moisture retention and a tender crumb. It gelatinizes at a similar temperature, helping to bind ingredients without adding density.
For best results, mix tapioca starch thoroughly with dry ingredients to ensure even distribution. Avoid overbaking, as tapioca starch can cause the bread to become slightly chewy if exposed to excessive heat.
Compared to arrowroot, tapioca starch produces a very similar texture and moisture level, making it the closest functional substitute in quick breads without altering flavor or appearance.
