Ajwain
UHJ-wine
Trachyspermum ammi
Also called carom seed, bishop's weed.
Sharp, thyme-like, pungent, bitter.
Ajwain, or carom seed, is the tiny seed of Trachyspermum ammi, a plant in the carrot family from the Indian subcontinent. Though the seeds look like miniature cumin, they taste powerfully of thyme, because they share the same compound, thymol, in a concentrated form. A little is intense and slightly bitter, so it is used sparingly, fried in oil for tempering or kneaded into flatbreads, savory pastries, and bean dishes. It is most at home in North Indian cooking, where it cuts richness and adds a sharp, herbal lift. Whole seeds keep their punch well.

How to handle it
Crackle a pinch of whole seeds in hot oil or work them into bread dough. They taste strongly of thyme, so use restraint.
Storage
Airtight and dark. Whole seeds hold their strong flavor for over a year.
Buying note
Tiny seeds with a powerful thyme smell when crushed. A small jar lasts a long time, since a pinch is enough.
Classic dishes
