Why it works: Cream and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Salt Mackerel
Ingredients
Directions
Prepare the fish
To freshen the mackerel, soak it skin side up in a stone crock of water overnight, changing the water before bed.
In the morning, rinse the mackerel in clear water.
Cook and serve
In a frying pan, boil the mackerel in a mixture of vinegar and water for about 5 minutes.
Carefully transfer the mackerel to a platter.
Heat the cream or milk with butter in a basin and pour it over the mackerel.
Serve with slices of lemon.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salt mackerel
- The main fish; soaking draws out excess salt so it can be eaten.
- Vinegar
- Its acidity gently firms the fish and adds a sharp, bright flavour.
- Cream or rich milk
- Fat and milk solids add richness and mellow the salty, sharp flavour.
- Butter
- Adds fat and a rich, savoury flavour to the warm cream sauce.
The step that matters
Changing the soaking water. Salt mackerel is very salty, and soaking it in fresh water overnight draws salt out of the flesh. Changing the water keeps the salt gradient steep so the fish keeps freshening; using stale water would leave it too salty.
Swap the lemon

Fit is the average pairing score against vinegar, cream, butter. Candidates are from the same food group and used in at least 100 recipes.
