Tapioca starch is a fine, silky powder extracted from the cassava root, used to thicken pie fillings, soups, and sauces to a glossy, clear finish. One metric cup (250 ml) weighs around 120 grams or 4.23 ounces. When a recipe gives tapioca in cups and your packet reads grams, converting by weight stops a filling turning runny or rubbery.

Tapioca starch is light and powdery, so a scooped cup can vary by several grams depending on how it packs. Weighing it keeps fruit fillings and sauces setting to the same gloss every time.

Related Tapioca Starch Ingredients

Corn flour (cornstarch) and tapioca starch both thicken at a 1:1 rate, though tapioca is a little lighter per cup (120 g vs 135 g corn flour). Tapioca sets glossier and clearer and freezes and thaws without weeping, while corn flour is cheaper and clouds slightly. See what 1 ounce of corn flour is in US cups.

Arrowroot and tapioca starch are close cousins, both clear-setting root starches that swap 1:1. Arrowroot is a touch denser per cup (128 g vs 120 g) and sets a firmer gel, while tapioca gives a stretchier, glossier finish good for pie fillings. See what 1 ounce of arrowroot is in US cups.
