Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Gravies for Fried Fisii
Ingredients
Directions
Prepare
Remove the fried fish pieces and place them in a stewpan with water or broth.
Fry the coated onions in the butter until brown, then add to the stewpan.
Make the gravy
Add the small piece of butter or cream, sweet herbs, and seasonings.
Let the mixture stew until it thickens to the consistency of raw cream, reducing the liquid by one-third.
Optionally, add pickled onions, mushrooms, and oysters, including the oyster liquor if using fresh.
For added flavor, include 1-2 glasses of wine.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onion
- Browns and sweetens, adding depth and body to the gravy.
- Butter
- Adds richness and fat, carrying flavor and giving the gravy a smooth finish.
- Flour
- Coats the onions and thickens the liquid as it stews into a gravy.
The step that matters
Stewing until thickened. The gravy must reduce by about one-third to reach the consistency of raw cream. Stopping too early leaves it thin, while over-reducing makes it stiff, so watch it closely as the liquid evaporates.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (fish, butter, pepper, nutmeg, lemon, sauce, mushroom):
- Shallotfits better
- Capsicumfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against fish, butter, pepper, nutmeg, lemon, sauce, mushroom. Candidates are from the same food group and used in at least 100 recipes.
