Measuring Cornstarch Accurately
Why weight matters: 2 tablespoons of cornstarch can weigh anywhere from 14g to 19g depending on how you measure it. The USDA standard is 16g (spooned and leveled). Scooping directly from the container can add 10–20% extra weight, which affects recipe results — especially in baking.
About cornstarch density: Cornstarch (corn flour in UK) is a fine white powder. 1 cup = 128g. Used as a thickener for sauces and gravies. 1 tablespoon cornstarch = 2 tablespoons all-purpose flour as a thickener.
About 2 Tablespoons as a Measurement
2 tablespoons = 30ml = 1/8 cup. This is the standard serving size for peanut butter, salad dressing, and most nut butters. 2 tablespoons is also the standard amount for a single packet of dry active yeast (about 7g).
Two tablespoons is the standard recipe unit for fats (butter, oil) in small-batch recipes, condiments (mustard, mayo), and sweeteners (maple syrup, honey) for a single serving. It is exactly 30ml or 1 fluid ounce.
Frequently Asked Questions
How many grams is 2 tablespoons of cornstarch?
2 tablespoons of cornstarch weighs 16 grams (0.56 oz, 30ml). Based on USDA FoodData Central: 1 cup cornstarch = 128g, so 2 tablespoons = 128 × 0.125 = 16g.
Is 2 tablespoons of cornstarch the same weight every time?
The weight can vary slightly depending on measuring technique. Spooned and leveled gives 16g. Scooped (packed) can be 10–20% heavier. Sifted gives a lighter weight. The USDA standard (spooned and leveled) of 16g is the most reliable baseline for recipes.
How do I accurately measure 2 tablespoons of cornstarch?
For accuracy, use a kitchen scale and weigh 16g of cornstarch. If using measuring cups, spoon the cornstarch lightly into a 2 Tablespoons measuring cup and level off the top with a straight edge. Avoid scooping directly from the container, which compacts the ingredient and adds extra weight.
How does 2 tablespoons of cornstarch compare to other ingredients?
