Why Does 1 Cup of Arrowroot Powder Vary?

The weight of 1 cup depends on how you measure. USDA standard (spooned) = 128g.

🥄

Spooned & Leveled

Spoon the ingredient into the measuring cup, then level off with a straight edge. This is the standard method used by USDA FoodData Central.

Reference weight
☁️

Sifted

Sift the ingredient first, then spoon into the cup. Sifting aerates the ingredient, reducing weight by 10-20%.

~10-20% lighter
📦

Scooped (packed)

Dip the cup directly into the bag and pack. This is the most inaccurate method — can be 20-30% heavier than spooned.

~20-30% heavier

About Arrowroot Powder Density

Arrowroot powder: 1 cup = 128g — similar density to cornstarch. Starch from the arrowroot plant (Maranta arundinacea). Great thickener for fruit-based sauces. Unlike cornstarch, stays clear and glossy when cooled. Substitute: 1 tsp arrowroot = 1 tsp cornstarch for thickening.

⚖️

Pro tip: For consistent baking results, use a kitchen scale. Weight measurements eliminate the variability of cup measurement entirely. USDA values shown are based on the spooned & leveled method.
