โญ Tapioca Starch (Best Nut-Free Option)
1:1 (replace arrowroot powder by weight)Tapioca starch is chemically similar to arrowroot powder and provides excellent binding and moisture retention, which is critical in bagel dough to achieve the characteristic chew and shiny crust. It gelatinizes at a similar temperature and creates a smooth texture.
When substituting, use equal amounts by weight to maintain dough consistency. Be mindful that tapioca starch can sometimes create a slightly more elastic dough, so monitor hydration levels.
Compared to arrowroot, tapioca starch yields a very close texture and appearance in bagels, preserving the chewiness and crust gloss without introducing off-flavors.
