Everyday Ratios
Why cooks trust our numbers
Sourced densities
Ingredient weights cross-checked against USDA FoodData Central, King Arthur Baking, and published culinary references — not crowdsourced guesses.
USDA safety temps
Every cook-time tool shows the USDA safe internal temperature, so time estimates never replace a thermometer.
Tested math
Formulas use baker's percentages, real pan-area geometry, and the same ratios professional kitchens rely on every service.
