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 ↓
Fish Stewed with Wine
Ingredients
Directions
Make the stew
Combine fish, wine, water, sliced onions, toasted bread, salt, pepper, and butter in a kettle.
Cover with enough water to cook and stew gently.
Make the sauce and serve
Before serving, pour the gravy into a saucepan.
Roll butter in flour to thicken, then add ketchup and walnut pickle; stir until smooth.
Pour the sauce over the fish to heat and serve hot. Add an anchovy if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the gravy when rolled with butter and cooked into the sauce.
- Butter
- Adds fat and richness to the stew and helps thicken the sauce with flour.
- Onions
- Soften during stewing and add sweetness and body to the gravy.
- Fish
- Forms the main protein, cooking gently until tender in the stew.
The step that matters
Stewing gently. Gentle heat keeps the fish tender and intact, while a hard boil can break it apart and toughen the proteins. Thickening the sauce with a flour and butter roux needs stirring so lumps do not form.
Swap the onion
How well each one fits the dish's main ingredients (fish, wine, bread, pepper, butter, flour, ketchup):
- Shallotfits better
- Capsicumfits better
- Tomatofits better
- Onionthe original
Fit is the average pairing score against fish, wine, bread, pepper, butter, flour, ketchup. Candidates are from the same food group and used in at least 100 recipes.
