How to Measure Cornstarch Correctly
Cornstarch is a powerful thickener - use 1 tablespoon per cup of liquid for medium thickness.
Mix cornstarch with cold liquid before adding to hot mixtures to prevent lumps.
Cornstarch mixed with all-purpose flour (2 tbsp per cup) makes a good substitute for cake flour.
238g of cornstarch is about 1 cup - that's 1 full cup plus a full cup of another.
Why Accurate Cornstarch Measurement Matters in Baking
A 10g error when measuring cornstarch can change your result by 0.08 cups. That's the difference between a perfectly balanced recipe and one that turns out too dry or too wet.
Adding just 10 extra grams of cornstarch (the weight of about one tablespoon) absorbs extra moisture and can turn a tender result into a dense, dry one. Conversely, using 10g less means your structure may not hold.

Frequently Asked Questions - Cornstarch Conversions
Using the Spoon & Level method (recommended), 238g of Cornstarch equals 1⅞ cups. With the Dip & Sweep method, it's 1⅝ cups, and when sifted it measures 2¼ cups. We recommend weighing ingredients for best results, but if you're using measuring cups, the Spoon & Level method is the most accurate.
Yes, significantly. The same 238g of Cornstarch can measure anywhere from 1⅝ cups (dip & sweep) to 2¼ cups (sifted) - that's a 33% difference. This happens because dip & sweep compresses the ingredient, fitting more into each cup, while sifting aerates it. For consistent baking results, always use the same method your recipe specifies.
Use the Spoon & Level method: fluff the Cornstarch in its container first, then lightly spoon it into your measuring cup until slightly overflowing. Level off the top with the flat edge of a knife. Never scoop directly from the bag - this compresses the ingredient and you'll end up with up to 20% more than intended.
It depends on how you measure. Using the Spoon & Level method, 1 cup of Cornstarch weighs approximately 128g. With Dip & Sweep, it's heavier at about 151g per cup. Sifted Cornstarch is lighter - about 109g per cup. This is why professional bakers prefer weighing ingredients in grams.
Not exactly. 2 cups of Cornstarch weighs approximately 256g. 238g equals about 1⅞ cups - roughly 18g less than 2 full cups. For precision in baking, it's worth measuring the exact amount rather than rounding to the nearest cup.
Yes. Sifting introduces air into the Cornstarch, making it lighter and fluffier. One cup of sifted Cornstarch weighs only about 109g, compared to 128g for spoon & level and 151g for dip & sweep. If your recipe calls for '1 cup sifted Cornstarch,' you need less by weight than '1 cup Cornstarch, sifted.'
No. Cornstarch is pure starch extracted from corn, while corn flour is finely ground whole corn. One cup of cornstarch weighs about 128g. They're not interchangeable - cornstarch is a thickener, while corn flour is used for baking.
238g of Cornstarch contains approximately 907 calories, 217.3g carbohydrates, 0.7g protein, and 0.2g fat. Per cup (spoon & level), that's about 488 calories. Values based on USDA nutritional data.
Use 1 tablespoon of cornstarch per cup of liquid for medium thickness. By weight, that's about 8g of cornstarch per 240ml of liquid. Mix cornstarch with cold liquid first to prevent lumps, then add to the hot mixture.
