Cornstarch substitutes depend on what job the starch is doing. Arrowroot is closest for clear fillings, tapioca gives a stretchier set, and flour is the fallback when clarity matters less than availability.
Use 1:1 for the closest result in most recipes.
Arrowroot is the closest all-purpose replacement because it thickens cleanly and usually behaves more like cornstarch than flour does.
View adjustment notes →Arrowroot keeps fillings clear, while tapioca creates a slightly stretchier, chewier set than cornstarch.
If cornstarch is used to soften a cookie, flour is not a true like-for-like swap and can make the cookie heavier.
When swapping starches, add heat gradually and stop once the mixture is fully thickened to avoid a gummy finish.

Pick substitutes that preserve tenderness, aeration, and even rise in cake batters.

Yes. Start with Arrowroot Powder at 1:1. Very similar behaviour. Better for acid-based and frozen sauces.
See recipe-specific answer →Top options are Arrowroot Powder (1:1) plus Tapioca Starch (Use 2 tbsp tapioca per 1 tbsp cornstarch) and All-Purpose Flour (Use 2 tbsp flour per 1 tbsp cornstarch).

Expect up to 6% variation in cup-based measurements due to brand and handling differences. Weight-first measuring is more reliable for structure-sensitive recipes.
