The combination of fish, potatoes and mustard reflects classic British comfort food, rooted in coastal towns where cod was a staple and potatoes provided cheap bulk. Adding horseradish and English mustard gives the dish a sharp, winter‑time flavor that was traditionally served in pubs and family meals.

Authentic ingredients include cod (or other white fish), English mustard, freshly grated horseradish, and dried sage. Substitutes can be haddock for the fish, Dijon mustard for a milder bite, and fresh sage instead of dried.

Serve it alongside buttered peas, a simple green salad with vinaigrette, or a classic British bread pudding for a full‑course dinner.
