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 ↓

Ingredients
Directions
Prepare the fish
Rub the flounders inside and out with salt and let them sit for 2 hours.
Make the broth
In a pot, combine the flounders, parsley leaves, parsley roots, peppercorns, and water. Boil until the fish falls apart.
Strain the mixture through a sieve to pulp the fish.
Cook and serve
In a separate pot, combine the pulped fish, the boiling liquid, and additional fish. Simmer until cooked through.
Serve in a deep dish with slices of bread and butter on the side.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flounders
- Provide the main fish flavor and body that gives the soup its substance.
- Parsley roots
- Add aromatic flavor to the broth as it simmers with the fish.
- Parsley leaves
- Contribute fresh herbal aroma to the broth.
- Peppercorns
- Add mild, warm pungency that rounds out the broth's flavor.
- Bread
- Soaks up the broth and adds body when served alongside the soup.
The step that matters
Pulping the fish through a sieve. Straining after the fish falls apart separates the flesh from bones and skin. Pressing it through leaves a smooth, cohesive body in the broth, so bones and fragments are not left in the soup.
Swap the parsley
How well each one fits the dish's main ingredients (bread, butter):
- Nutmegfits about as well
- Parsleythe original
- Capersfits about as well
- Sagefits about as well
Fit is the average pairing score against bread, butter. Candidates are from the same food group and used in at least 100 recipes.
