"Finding recipes is easy. Understanding why flavors work together, discovering your dish has a twin 6,000km away, and exploring the molecular science behind every bite -- that's what's missing."
With 118,000+ recipes across 74 countries in RecipeDB and 25,595 flavor molecules in FlavorDB, the data exists. But no one has connected these datasets to reveal the hidden molecular relationships between the world's cuisines. FlavorPrint bridges this gap.
Search 118K+ recipes by title, view Recipe of the Day, track search history with smart caching.
Find recipes from different countries that share the same molecular fingerprint. "This Thai Pad Thai and an Italian Burger share 37% molecular identity." Suggestion chips for quick access.
Classify any recipe on the Pairing vs Contrast spectrum (Ahn et al., 2011). Western cuisines pair ingredients sharing molecules; East Asian cuisines contrast them. Full radial FlavorPrint visualization.
Compare molecular profiles of up to 3 cuisines side-by-side. 5 preset combos (e.g. Indian vs Japanese). Visualize flavor category breakdown with bar charts.
A black-themed experimental workspace with 6 sub-modules:
| Module | What it Does |
|---|---|
| Molecular Kitchen | Drag-and-drop ingredients into a beaker, see real-time molecular reactions |
| Formula Library | 55+ pre-built experiments across 10 cuisines with full molecular breakdowns |
| Compatibility Heatmap | Visual matrix of Jaccard similarity between ingredient pairs |
| Fusion Lab | Combine cuisines to generate novel fusion recipes with molecular backing |
| Live Molecular Analysis | Search ANY ingredient, get its full molecular profile with comparison mode |
| API Explorer | Browse & test all 62 FlavorDB + RecipeDB endpoints live |

Key Algorithms:
- Molecular Fingerprinting -- Aggregate flavor molecules per ingredient, classify into 8 categories, generate radial chart
- Cross-Cultural Twinning -- Jaccard similarity on molecule sets + low ingredient overlap = high twin score
- Philosophy Spectrum -- Average shared molecules per ingredient pair vs random baseline
- Ingredient Compatibility -- Pairwise Jaccard similarity heatmap across ingredient palette
We use both RecipeDB and FlavorDB extensively:
FlavorDB Endpoints (Entity, Molecule, Food Pairing, Property Controllers):
/entities/by-entity-alias-readable-- Search ingredients/entities/by-name-and-category-- Filter by category/entities/by-natural-source-- Filter by natural source/food/by-alias-- Food pairing suggestions/molecules_data/by-flavorProfile-- Molecules by flavor/molecules_data/by-commonName-- Molecule lookup/molecules_data/filter-by-type-- Chemical type filter/properties/by-description-- Property search/properties/taste-threshold-- Taste threshold filter
RecipeDB Endpoints:
/recipe-bytitle/recipeByTitle-- Search 118K+ recipes/search-recipe/{id}-- Full recipe details/instructions/{recipe_id}-- Cooking instructions/recipe/recipeofday-- Recipe of the Day/recipe/recipesinfo-- Paginated recipe list/recipes_cuisine/cuisine/{region}-- Filter by cuisine
62 total endpoints documented and testable in our API Explorer.
During development we documented several API bugs and gaps. See ISSUES.md for the full report including:
- Entity endpoint returning metadata without molecules
- Parameter naming inconsistencies (camelCase vs snake_case)
- Missing entity-to-molecules mapping endpoint
