Q: Why do grams matter more than cups for baking?

Cups measure volume, not weight. The same cup can hold vastly different weights depending on how tightly the ingredient is packed. For example, a loosely scooped cup of flour might weigh 110g while a firmly packed cup weighs 150g — a 36% difference that affects the final bake. Weighing in grams gives consistent, reproducible results every time.
