Frequently asked questions
How many grams is 1/3 cup of cornstarch?
1/3 cup of cornstarch is 40 grams, based on 120 g per level US cup.
Is it different with a UK or Australian cup?
Slightly. UK, Australian and New Zealand recipes use a 250 ml metric cup, which is about 6% bigger than a US cup (236.6 ml). Using a metric cup, 1/3 cup of cornstarch would be 42 g.
Should I weigh cornstarch or measure it by volume?
Spoon flour into the cup and level it with a knife. Scooping straight from the bag packs it down and can add 20–30% more. Weighing is always more accurate, which is why grams are the safest choice for baking.
