Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Herrings
- The main protein; its oily flesh cooks quickly over direct heat and stays moist.
- Salad oil
- Coats the fish during soaking, carrying seasoning and helping prevent sticking on the grill.
- Butter
- Forms the base of the sauce, adding richness and a smooth, silky texture.
- Mustard
- Adds sharp, pungent flavour that cuts through the richness of the fish and butter.
The step that matters
Grilling the herrings over a clear fire. Herring is oily and delicate, so the fire should be clear and steady rather than flaming. Flare-ups char the skin before the flesh is cooked through, and the scoring helps heat reach the thick parts evenly.
