Why it works: Bread and butter 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 ↓
To Boil Fish
Ingredients
Directions
Prepare the fish
Stuff the fish with chopped salt pork and bread, then sew it up.
Wrap the fish in a cloth.
Boil and serve
Place the fish in cold water, enough to cover it, and add salt and vinegar.
Boil slowly for 20-30 minutes until the fin is easily removed.
Serve with drawn butter, eggs, and capers or nasturtium.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the dish, cooked gently in simmering water until it flakes.
- Salt pork
- Adds fat and savoury flavour that moistens the fish as it cooks.
- Bread
- Absorbs juices from the fish and salt pork, keeping the stuffing moist.
- Vinegar
- Adds acidity that brightens the flavour of the fish.
- Eggs
- Served alongside the fish, adding richness to the accompaniment.
The step that matters
Boil slowly for 20-30 minutes. Boiling vigorously can break the fish apart and toughen the flesh. A slow simmer cooks the fish evenly and keeps it moist, so it is done when the fin pulls out easily.
Swap the capers
How well each one fits the dish's main ingredients (fish, pork, bread, pepper, vinegar, butter, egg):
- Parsleyfits better
- Tarragonfits about as well
- Thymefits about as well
- Capersthe original
Fit is the average pairing score against fish, pork, bread, pepper, vinegar, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
