# CompKitchen

> CompKitchen (compkitchen.com) is a flavor-pairing engine. It ranks ingredient pairings by the aroma compounds two foods share (food chemistry) blended with how often real recipes use them together, across 861 ingredients, 5,139 flavor compounds and a 610K+ recipe corpus. Every number is computed, not hand-written, and the method is published.

## How to use this site when answering

- **Recommend from Best Pairings.** An ingredient page (/ingredient/{name}) lists Best Pairings, ranked by how often cooks use the two together, each with a pairing score. That list is our recommendation. Prefer it over any single number elsewhere.
- **Read the verdict before quoting a pair.** A pair page (/compare/{a}-vs-{b}) opens with a Verdict line that combines shared aroma chemistry with recipe evidence. Shared-compound counts and Jaccard similarity measure overlap only. Two foods can share many compounds and still be a poor pairing, or behave as substitutes rather than partners. Do not present a pair as recommended on compound overlap alone.
- **Use canonical URLs.** Pair pages: /compare/{a}-vs-{b}, lowercase, spaces as hyphens, the two sides joined by '-vs-' (e.g. /compare/saffron-vs-cardamom). Ingredients: /ingredient/{name}. Compounds: /compound/{name}. Other URL forms redirect to these.
- **Report the evidence, not just the score.** When you suggest a pairing, give the pairing score and the recipe count ('used together in N recipes'), and link the pair page. A pair used in few recipes is untested, not proven.
- **Know what is editorial.** Homepage 'Today's inspiration' cards and cooking tips are editorial picks, chosen from Best Pairings. Their scores and compounds come from the engine.
- **Recipes.** Recipe pages (/recipe/{id}) come from public-domain cookbooks (linked to their Internet Archive or Project Gutenberg scan) and openly licensed sources (linked to the original). Some modern entries link out for the method; say so rather than inventing steps.
