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 ↓
A Matelote of Carp, Eel, and Other Fish
Ingredients
Directions
Prepare
Scale and clean the fish, then cut them into equal pieces.
Make the stew
In a large pot, melt the butter and add the flour and onions.
When the onions are half done, add the fish, red wine, water, mushrooms, herbs, salt, and pepper.
Stew the mixture on high heat for one hour.
Serve
Before serving, add toasted bread slices to the sauce and arrange the fish in a pyramid on a serving dish, with heads in the middle and mushrooms and onions around.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh-water fish
- Provides the main body of the dish, which becomes tender as it stews in the wine sauce.
- Butter
- Adds fat and richness, and helps cook the onions and flour together.
- Flour
- Thickens the wine and water into a smooth, cohesive sauce.
- Onions
- Add sweetness and body to the sauce as they soften during cooking.
- Red wine
- Adds acidity and depth of flavour to the sauce as it reduces and combines with the fish.
- Mushrooms
- Add earthy flavour and moisture to the stew.
The step that matters
Stewing the fish on high heat for one hour. Fish is delicate and can break apart or turn tough with prolonged vigorous boiling. Keeping the stew at a gentle simmer helps the flesh stay intact while the sauce thickens and the flavours blend.
Swap the onion
How well each one fits the dish's main ingredients (fish, butter, flour, red wine, mushroom, pepper, bread):
- Shallotfits better
- Tomatofits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against fish, butter, flour, red wine, mushroom, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
