Quality & Sensory

Each batch is carefully cleaned and dried to preserve its small, dark, glossy seed form and mild pungent aroma. When decocted, the seeds release a gentle, warming scent with a subtly sharp, onion-like note; when milled, the powder carries a fine texture and a fuller, more concentrated aroma that blends easily into teas and soups.
