Trachyspermum ammi

A tier

Trachyspermum ammi is the botanical species behind ajwain—tiny ridged fruits that pack a thymol-heavy wallop far beyond their size. The aroma hits like oregano crossed with caraway, then finishes hot and medicinal if you chew a seed raw. Whole seeds stay potent for months; ground ajwain fades within weeks. Temper in hot ghee or oil until the seeds darken a shade and the kitchen smells of pizza herb and pepper—then add potatoes, dals, or chickpea batters. Rajasthani and Gujarati cooks lean on this species as a digestive spice for heavy lentil and fried snacks. Never confuse the living plant with true bishop’s weed of other genera; culinary ajwain is this Apiaceae species.
