How scaling works
Each ingredient amount is multiplied by target servings ÷ original servings. Results snap to the nearest kitchen-friendly fraction, and unit amounts roll up when they get bulky (48 teaspoons becomes 1 cup). Baking is less forgiving than cooking — for flour-forward recipes, see our baking ratio reference.
