Walnut is a nut with 324 known flavor compounds. The most distinctive molecule is farnesane. It pairs most strongly with vanilla, sharing 221 flavor compounds. Walnut appears in 13,186 recipes, most commonly in world cuisine.
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), Walnut's inventory contains 53. Most of the other 271 compounds are below detection threshold.
+ 41 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 Walnut's 324 known compounds break down by aroma category. Percentages are of compounds with a known label.
76 of 324 are distinctive to walnut — they appear in under 10% of foods. The remainder are the background most foods share.
Ordered by measured impact in walnut — 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 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. For the chemistry-first view — where the surprising pairings live — see the molecular network below, the side-by-side comparison, or the Pairing Tool.
