About Nibbleboard

Our Data

We maintain a database of over 3,000 cooking ingredients, each with per-100g nutritional data sourced from the USDA FoodData Central database — the same source used by food manufacturers for nutrition labels.

Grocery prices are collected weekly from 15+ online grocery markets across the United States. We compute per-unit costs, then calculate recipe costs by summing the actual ingredient amounts used. This means our "cost per serving" figure reflects what you'd actually spend at the store — not a rough estimate.

How Recipe Nutrition Is Computed

Every recipe's nutrition label is computed server-side, not entered manually. Here's the process:

1. 1Each ingredient's measurement (cups, tablespoons, pieces) is converted to grams using standardized USDA conversion factors.
2. 2The per-100g nutritional values (calories, protein, carbs, fat, fiber, sugar, sodium) are scaled to the actual amount used.
3. 3All ingredient contributions are summed and divided by servings to produce per-serving nutrition values.
4. 4Dietary flags (vegan, vegetarian, gluten-free, dairy-free) are determined by logical AND — a recipe is only marked vegan if every ingredient is vegan.

Our Tools

We build free tools that help you cook smarter and spend less:

Editorial Standards

Our recipes are tested and reviewed before publication. Every recipe goes through quality validation that checks:

• ✓ Ingredient amounts are within realistic ranges
• ✓ Cooking times match the method and difficulty level
• ✓ Nutrition values fall within expected ranges for the meal type
• ✓ All ingredients exist in our database with verified nutrition data
• ✓ Cost computations use current market prices
