- Using volume-only measurements for dense ingredients can overshoot recipe targets.
Brand Variance Example
Baseline on this page: 1 cup onion powder = 130g. Real-world range can shift by about 10% because particle size and settling vary across brands and freshness windows.
Example for 2 cups: baseline 260g, common range 234g-286g. If your bake is texture-sensitive, start with the lower bound and adjust after a test batch.
