Why Cup-to-Grams Accuracy Matters for Cornstarch
Small cup changes create big weight differences. For cornstarch, 1/3 cup is about 43g, but just 1/4 cup more jumps to 75g.
This is why cup-based recipes can drift: packed, loose, or sifted volume can shift your actual grams. Using grams keeps hydration and texture consistent across batches.
