About Cornstarch
Cornstarch is a fine, white powder extracted from corn kernels. It is used as a thickener in sauces and fillings, and as a cake flour substitute when combined with all-purpose flour. Its density is 0.541 g/ml. It is also commonly known as corn starch or cornflour.
Cornstarch has a density of 0.541 g/ml when measured using the Spoon & Level method. Like all dry ingredients, the measurement method significantly affects the volume.
This ingredient belongs to the other category and is classified as a dry ingredient. Per 100g, it provides 381 calories,0.3g protein, 91.3g carbohydrates, and 0.1g fat.
Density data sourced from USDA FoodData Central. US Cup = 236.588ml (NIST). Results are estimates - actual volume may vary by ±5% depending on brand and batch.

Using the Spoon & Level method, 125g of cornstarch equals approximately 0.98 cups. Cornstarch has a density of 0.541 g/ml, similar to all-purpose flour.
Yes, but use half the amount. Cornstarch has twice the thickening power of flour. Mix it with cold liquid first to prevent lumps.
Replace 2 tablespoons of all-purpose flour per cup with 2 tablespoons of cornstarch. The cornstarch dilutes the protein content, mimicking cake flour's lower protein level.
