โญ Tapioca Starch (Best Fat-Free Option)
1:1 by volume (e.g., 1 tablespoon tapioca starch per 1 tablespoon arrowroot powder)Tapioca starch is a fine, gluten-free starch that gelatinizes at a similar temperature to arrowroot, providing excellent thickening and a shiny, smooth texture. It helps the custard adhere well to the bread, creating a tender crust without heaviness.
To ensure success, mix tapioca starch thoroughly into the egg mixture to avoid clumps. Avoid overheating as tapioca can become stringy if cooked too long at high heat.
Compared to arrowroot, tapioca starch produces a slightly chewier crust but maintains the desired lightness and moisture balance in the French toast.
