How This Nutrition Estimate Was Prepared
- Every ingredient is assigned a specific gram weight instead of relying only on a cup, spoon, or item count.
- 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.
Accuracy note: These values are approximate ingredient estimates, not independently verified nutrition analysis. Weigh ingredients and calculate from the labels on the exact brands used when precision is important.
