Sugar is an additive with 65 known flavor compounds. The most distinctive molecule is butyrolactone. It pairs most strongly with vanilla, sharing 40 flavor compounds. Sugar appears in 239,671 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), Sugar's inventory contains 12. Most of the other 53 compounds are below detection 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 Sugar's 65 known compounds break down by aroma category. Percentages are of compounds with a known label.
14 of 65 are distinctive to sugar — they appear in under 10% of foods. The remainder are the background most foods share.
Ordered by measured impact in sugar — 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.
