Arrowroot is a fine white starch ground from the root of the arrowroot plant, used to thicken sauces, fruit fillings, and glazes without clouding them. One metric cup (250 ml) weighs around 128 grams or 4.52 ounces. When a recipe lists arrowroot in cups but your packet only shows grams, converting by weight keeps a sauce from turning thin or gluey.

Arrowroot is a light powder that settles and compacts when scooped, so a cup measured by eye can swing by several grams. Weighing it gives a steadier thickening result across gravies, pie fillings, and custards.

Corn flour (cornstarch) is the everyday stand-in for arrowroot, and the two swap 1:1 as thickeners. Arrowroot sets clearer and copes better with acidic or frozen sauces, while corn flour is cheaper and clouds a little. They weigh close per cup (128 g vs 120 g). See our Corn Flour converter.

Tapioca starch is arrowroot's close cousin, another clear-setting root starch that swaps 1:1. Tapioca is a little lighter per cup (120 g vs 128 g) and sets a stretchier, glossier gel, while arrowroot sets firmer and copes well with acidic sauces. See our Tapioca Starch converter.
