}Explanation
Use 112 g per US cup as the reference when converting cornstarch from cups to grams.
Recipe scaling stays tied to the US cup standard (236.588 mL) rather than to mixed cup charts. Cornstarch can vary with fineness, aeration, and settling, so the page keeps one fixed basis for repeatable measuring.

Methodology
Cornstarch: cups to grams evidence
Cornstarch is a neutral starch derived from corn, used primarily as a thickening and stabilizing agent rather than a flavoring ingredient.
Practical use: Cornstarch is used as a technical thickener and stabilizer in syrups, sauces, creams, and culinary-style preparations associated with modern or dessert-oriented drink builds. It is not used as a direct cocktail ingredient but as a behind-the-scenes texture modifier.
Ingredient characteristics: Cornstarch is flavor-neutral and aroma-free. It contributes no sweetness, bitterness, acidity, or aroma, functioning solely as a textural agent that increases viscosity and smoothness when hydrated and heated.
Direction calculation: Cornstarch — 1 US cup equals 112 grams. Reference: 112 g/US cup. Source basis: King Arthur weight chart (¼ cup=28g)
Among the 5 reviewed records labeled Starches, the nearest factor to Cornstarch is Tapioca Starch at 113 g/cup: a difference of 1 g/cup (0.9% relative to Cornstarch). The observed range in this labeled group is Cornstarch at 112 g/cup to Rice Starch at 160 g/cup.
Particle size, aeration, settling, and whether the cup is scooped or spoon-filled can materially change the mass held by the same volume.
