Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Red herrings
- Provide the main fish, which the beer soak moistens and flavours.
- Small beer
- Soaks into the herrings, adding moisture and a malty flavour.
- Cold butter
- Melts over the warm herrings, adding richness and a glossy finish.
- Mashed potatoes
- Serve as a starchy side that soaks up the herring juices and butter.
The step that matters
Heating the herrings gently. Over strong heat the fish can dry out or break apart before it is warmed through. Gentle heat keeps the moisture the beer soak added, so the fish stays tender.
Swap the potato
How well each one fits the dish's main ingredients (beer, butter, egg, sauce, bread):
- Capsicumfits better
- Tomatofits about as well
- Shallotfits about as well
- Potatothe original
Fit is the average pairing score against beer, butter, egg, sauce, bread. Candidates are from the same food group and used in at least 100 recipes.
