Why it works: Onion and potato are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
New Orleans Court Bouillon
Ingredients
Directions
Make the sauce
Fry 3 chopped onions in a tablespoon of butter.
Add a cup of tomatoes, 3 or 4 whole cloves, pepper, salt, and toast to the onions.
Let the mixture stew together for 30 minutes.
Add 1 tablespoon flour and about ½ pint of claret to the stew.
Let it boil, stirring constantly, for 5 minutes until the flour is thoroughly cooked.
Strain the sauce and return it to the fire in a saucepan.
Cook the fish and serve
Lay slices of fish in the sauce and let them simmer gently until cooked, about 6 to 10 minutes depending on thickness.
Prepare a deep dish with slices of toast enough to cover the bottom.
When the fish is done, lay the slices of fish on the toast.
Add the remaining 1 pint of claret to the sauce and pour it over the fish.
The Court Bouillon is ready to serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the sauce as it boils and cooks through.
- Claret
- Adds liquid and wine flavour to the sauce.
- Onions
- Build the flavour base of the sauce when fried in butter.
- Tomatoes
- Add acidity and body to the sauce.
The step that matters
Boiling the flour and claret mixture. Flour must be stirred constantly and boiled for the full five minutes so it cooks through; otherwise it keeps a raw, pasty taste and fails to thicken the sauce smoothly.
Swap the clove
How well each one fits the dish's main ingredients (flour, sauce, butter, tomato, onion, potato, egg):
- Capersfits better
- Garlicfits better
- Parsleyfits better
- Clovethe original
Fit is the average pairing score against flour, sauce, butter, tomato, onion, potato, egg. Candidates are from the same food group and used in at least 100 recipes.
