Curry powder is a ready-mixed, turmeric-forward spice blend — a British-Indian invention rather than a single Indian spice — built to give a warm, golden, savoury "curry" flavour from one tin. Earthy and aromatic with a mustardy, faintly bitter base and a mild-to-hot finish, it leans on turmeric for colour, coriander and cumin for body, and fenugreek for its characteristic sweetish, maple-curry note.
