Crab is a seafood with 90 known flavor compounds. The most distinctive molecule is heptanone. It pairs most strongly with meat, sharing 24 flavor compounds. Crab appears in 1,733 recipes, most commonly in creole cuisine.
Meaty nutty popcorn-like scent with potato and geranium notes. Heat triggers oxidation producing Maillard meaty aromas.
Compounds ranked by rarity — the higher the score, the more distinctive to this ingredient.
Of the ~226 molecules that drive perceived food aroma (Dunkel et al. 2014), Crab's inventory contains 18. Most of the other 72 compounds are below detection threshold.
+ 6 more — showing top 12 by class and threshold.
Generalist = appears in >25% of foods (Maillard / fermentation products). Individualist = appears in <5% of foods (carries signature notes). Threshold values are in clean water — the actual perception threshold in a food matrix can differ substantially.
How Crab's 90 known compounds break down by aroma category. Percentages are of compounds with a known label.
14 of 90 are distinctive to crab — they appear in under 10% of foods. The remainder are the background most foods share.
Ordered by measured impact in crab — concentration against odour threshold where both are published, then by how distinctive the molecule is across the graph. Molecules measured here but not established as odorants sit below those that are.
Ranked by median concentration across published studies. Only 2 of Crab's 90 compounds have a measured concentration in the literature — the rest are confirmed present but not yet quantified. Bars are log-scaled.
Ranked by how often cooks actually use them together, across 453,403 recipes — the familiar answer first. Each pairing still carries its molecular score and shared-compound count; only the ORDER differs. Counts cover every characterised molecule the two ingredients have in common, not only the aroma-active ones, so they can exceed an ingredient’s aroma-compound count.
