Marjoram vs Oregano: shared flavor compounds
274 of 361 flavor compounds are shared (Jaccard 0.76) — the molecular basis for whether Marjoram and Oregano pair well or work as substitutes. Full side-by-side breakdown below.
“Reported” counts reflect the compounds characterized for each ingredient across the studies and databases we aggregate — a measure of coverage, not an exhaustive census. Different analyses target different compound classes and methods, so read these as what has been characterized, not the total number of molecules present. Jaccard measures shared coverage, so it rewards overlap rather than highlighting the ratio differences that distinguish two ingredients.
Why they pair: shared-compound network
12 of 274 shared shownEach molecule in the middle is shared by both ingredients — the chemistry bridging Marjoram and Oregano. Node color is chemical class and node size is perceptual potency (bigger = lower odor threshold, so it drives aroma at smaller amounts); a copper ring marks compounds flagged as key aromas in published GC-O studies. Zoom with the +/− buttons or a pinch, drag the background to pan, drag a node to pin it, click any molecule for its full profile.

Where they differ: aroma character
Profile distance 0.04The Jaccard above measures overlap; this compares each ingredient’s aroma-family mix side by side — the wider the gap between the two bars, the more that family sets the ingredients apart. Marjoram reads left, Oregano reads right.
Shares are fractions of each ingredient’s labeled compounds (276 of 306 for Marjoram, 291 of 329 for Oregano) — compositional lean, not concentration. Aroma labels come from our compound enrichment and cover most, but not all, characterized molecules.
Pro names the molecules behind each difference — the specific compounds in each aroma family that one ingredient has and the other doesn’t. Sign in to see them.
