Why Cup-to-Grams Accuracy Matters for Cornstarch

Small cup changes create big weight differences. For cornstarch, 2 cups is about 256g, but just 1/4 cup more jumps to 288g.

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.

If your recipe starts in cups, convert once to grams and bake by weight. That avoids hidden volume error and makes your result repeatable every time.
