Tapioca Starch (Best Option)
1:1 (1 tablespoon tapioca starch per 1 tablespoon arrowroot powder)Tapioca starch has a similar amylopectin content to arrowroot powder, which helps in creating a stretchy and crisp dough by gelatinizing during baking. This starch enhances moisture retention and elasticity, important for a good pizza crust.
When substituting, ensure the starch is well incorporated to avoid clumping. Tapioca starch can sometimes brown faster, so monitor baking times closely.
Compared to arrowroot, tapioca starch yields a slightly chewier crust but maintains the lightness and crisp texture expected in pizza dough.
