Why does peanut butter weigh what it weighs?
Sticky and pasty condiments like peanut butter, tomato paste, and jam are notoriously hard to measure by volume — air pockets and clinging residue throw off cup readings. Weighing directly into the mixing bowl saves a measuring cup from the dishwasher and gives a clean, reproducible result.
For peanut butter specifically, 1 cup weighs 258g. 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.
