Why does potato starch weigh what it weighs?
Pure starches like cornstarch and tapioca are extremely fine and pack tightly. A heaping spoonful versus a leveled one can mean a 50% difference in thickening power — the difference between a glossy sauce and a gummy one. Always level when measuring by volume, or weigh for true precision.
For potato starch specifically, 1 cup weighs 152g. 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.
