Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Herrings
- Form the main body of the dish and carry the smoky char from the grill.
- Salad oil
- Carries the pepper and salt into the fish and helps keep the flesh moist on the grill.
- Butter
- Melts into a rich, smooth base for the mustard sauce.
- Raw mustard
- Adds sharp, pungent flavour that cuts the richness of the fish and butter.
The step that matters
Grill the herrings over a clear fire. Herring is oily and delicate, so it can stick or dry out if the fire flares or is uneven. A clear, steady heat cooks the flesh through while keeping the skin crisp and the fish moist.
