Bunium persicum

A tier

Bunium persicum is the botanical identity behind much of what markets call black cumin or shahi jeera in the Persian and North Indian highlands—narrower, darker, more curved seeds than Cuminum cyminum, with a sweeter, smokier, slightly floral aroma. It is a different genus, not a colour form of true cumin, which is why swapping equal volumes can surprise a cook expecting standard jeera. Wild and cultivated stands in Iran, Afghanistan, and Kashmir shaped its prestige pricing. Bloom gently; the delicate oils scorch faster than bulk white cumin. Use in rice pilafs, rich meat gravies, and royal-style Mughlai dishes where shahi jeera is traditional. Do not confuse with Nigella sativa (kalonji), another “black cumin” in loose speech. Buy whole dark slender seeds from spice specialists and grind fresh.
