Why it works: Pepper and onion are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
French Anglers' Way of Stewing Fish
Ingredients
Directions
Prepare
Cut the fish into medium-sized pieces.
In a stewpan, combine fish, salt, pepper, sugar, and sliced onions.
Stew
Add wine and water, then set on the fire to stew, gently tossing occasionally.
Check for tenderness by feeling the pieces with your finger.
Thicken and finish
Mix flour with butter, adding bit by bit to the pan while shaking it gently.
Boil for a few more minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the body of the stew and becomes tender as it simmers in the liquid.
- Onions
- Soften during stewing and add sweetness and body to the broth.
- Flour
- Thickens the cooking liquid so the stew has a light, smooth body.
- Butter
- Adds richness and fat, and helps the flour blend smoothly into the liquid.
- Wine
- Adds acidity and flavour to the stewing liquid.
The step that matters
Adding the flour and butter. Flour added directly to hot liquid clumps. Mixing it with butter first and adding it bit by bit while shaking the pan lets it disperse and thicken evenly.

Fit is the average pairing score against fish, pepper, sugar, wine, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
