Why it works: Bread and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and 27,232 recipes mention both. Both carry delta-decalactone, which smells sweet, creamy. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Herring
- The fish is the main component, cooked until firm and golden on the outside.
- Flour
- Coats the fish and thickens the sauce so it becomes short and brownish.
- Grated bread
- Forms a crisp, browned coating on the outside of the fish when fried.
- Bacon
- Adds fat and savory flavor to the sauce as it softens with the onion.
- Onion
- Adds sweetness and savory depth to the sauce as it simmers.
- Butter or lard
- Fat for frying that browns the coated herring and carries flavor.
The step that matters
Fry the herring until golden brown. The flour and bread coating must be dry and the fat hot enough to brown the crust quickly; otherwise the coating turns soggy or greasy and the fish can overcook before it browns.

Fit is the average pairing score against flour, bread, butter, pepper, white wine, vinegar, fish. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
