- Standard unbranded food-composition values are aligned with the closest matching foods in USDA FoodData Central.
- Ingredient values are added for the full recipe, divided by the listed yield, and rounded only for display.
- Optional ingredients are excluded unless a measured amount is included in the base recipe.
