Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Fish Cutlet
Ingredients
Directions
Prepare the fish
Boil the fish in salted water for 10 minutes per pound.
Remove the fish, let it cool, and then flake it finely.
Make the mixture
In a saucepan, bring the milk to a boil.
In a bowl, mix the butter and flour together.
Add the butter-flour mixture to the boiling milk.
Stir in the chopped parsley and the egg yolks.
Add the flaked fish and mix well.
Season the mixture with salt, pepper, and optional ingredients.
Shape and fry
Once cooled, form the mixture into cutlets.
Roll each cutlet in flour.
Dip the cutlet in beaten egg.
Coat the cutlet with bread crumbs.
Fry the cutlets in hot oil until golden brown.
Make the sauce
For the sauce, melt butter in a pan. Stir in flour.
Add milk to the sauce.
Season the sauce with salt and pepper.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the cutlet and gives it its flavor.
- Milk or cream
- Binds the mixture with moisture, keeping the cutlets tender inside.
- Butter
- Adds richness and fat that softens the texture of the mixture.
- Flour
- Thickens the milk mixture so it holds together when shaped.
- Egg yolks
- Enriches the mixture and helps bind it into a firm cutlet.
- Egg
- Creates a sticky layer that helps bread crumbs adhere and brown when fried.
The step that matters
Let the mixture cool before shaping. A hot, loose mixture is too soft to hold its shape. Cooling lets the flour-thickened milk and egg yolks set, so the cutlets keep their form in the frying oil.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (fish, milk, butter, flour, egg, parsley, pepper):
- Potatofits better
- Shallotfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against fish, milk, butter, flour, egg, parsley, pepper. Candidates are from the same food group and used in at least 100 recipes.
