Profile
Ajwain, also written ajowan or carom seed, is the small ridged fruit of Trachyspermum ammi, an annual umbellifer of the Apiaceae family related to cumin and caraway. The seeds are greyish-green, 1 to 2 mm long, five-ridged, and astonishingly aromatic for their size: their essential oil is 35 to 60 percent thymol, the same molecule that gives thyme its scent. A single crushed seed throws a dense wave of oregano, thyme, and camphor across a dish. The plant is thought to have originated in the eastern Mediterranean and Iran, moved east along Achaemenid and Sasanian trade routes, and settled in India, where it has been cultivated since at least the early medieval period. India now produces roughly 90 percent of the world supply, concentrated in the semi-arid belts of Gujarat and Rajasthan, with smaller output in Iran, Afghanistan, and Pakistan.

Process
01October
Sowing
Trachyspermum ammi seeded into cool post-monsoon soil in Gujarat and Rajasthan — the classic rabi winter crop.
02December
Flowering
White compound umbels open on 60–90 cm plants, each flower head carrying dozens of future seeds.
03February
Seed fill
Schizocarps ripen on the umbel, turning from green to greyish-brown with a ridged, curved profile.
04March
Harvest
Umbels are cut at full maturity, stacked, and sun-dried in the cool winter light to preserve thymol.
05Threshing
Rubbing out
Dry umbels are beaten or lightly machine-rubbed; the twin mericarps separate, chaff is winnowed by wind.
06Your jar
Whole, bloomed in ghee
Store whole in glass. Bloom in hot ghee or oil for 5 seconds before adding to dough or dal — the thymol coats the fat and perfumes the dish.

The molecules that make it taste like Kampot — and not like anything else.
GC-MS of Trachyspermum ammi: thymol dominates at 35–60% of the essential oil — the reason ajwain smells like thyme on steroids. p-Cymene and γ-terpinene build the oregano-adjacent frame.

Frequent questions
Technically a fruit. What we call ajwain 'seeds' are the ridged, curved mericarps of Trachyspermum ammi, an Apiaceae umbellifer related to caraway, cumin and parsley. The tiny pale-grey grains are the dried schizocarp halves, not true seeds.
