Why does onion powder weigh what it weighs?
Ground spices vary by particle size — a tablespoon of freshly ground pepper weighs less than the same volume of pre-ground because freshly cracked pieces are larger and pack less tightly. Dried herbs are even more volatile, since whole leaves and crushed leaves occupy very different volumes. For high-stakes seasoning (curing meat, pickling brines), always weigh.
For onion powder specifically, 1 cup weighs 115g. That is the figure to plug into recipes calling for cup measurements when you want gram precision. ChefVault stores this density (and 118 others) so you never have to look it up twice.
Recipes that originated outside the United States almost always specify weight in grams. Translating these to US cup measurements introduces error in every step. The ChefVault app handles the math automatically — paste a recipe, hit convert, get a clean weight-based version.
