About Cornstarch
Cornstarch is a fine white starch used to thicken sauces, soups and gravies, and to lighten cakes and cookies. It has no flavor of its own, so it thickens without changing taste. Charts differ on cornstarch: some list 112 grams per cup from a quarter-cup measurement, while the standard converter value used here is 128 grams per cup. For thickening sauces, the difference rarely matters, but weigh it when accuracy counts.

Measuring Cornstarch in spoons
Spoon cornstarch into the measuring spoon and level it off, working slowly because the fine powder drifts into the air. Break up any lumps first, since a lumpy spoon holds less starch than a smooth one and thickens a sauce less.
Spoon amounts for Cornstarch
One tablespoon of cornstarch weighs 8 grams and one teaspoon weighs 2.7 grams. These values are derived from the same grams-per-cup value used on this page, so they agree with the cup chart above; they are not separate measurements.
| Spoons | Grams |
|---|---|
| 1 teaspoon | 2.7 grams |
| 1 tablespoon | 8 grams |
| 2 tablespoons | 16 grams |
| 3 tablespoons | 24 grams |
| 1/4 cup | 32 grams |
For amounts smaller than a teaspoon, or for baking where a few grams matter, weigh the ingredient instead of spooning it. Spoons are best for everyday cooking, where a gram or two either way changes nothing.
