Why it works: Pepper and parsley 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 Cutlets
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the fish base
Melt the butter in a saucepan over medium heat.
Stir in the flour and cook for 1 minute.
Gradually add the milk, stirring constantly until boiling.
Season with salt, pepper, onion juice, Worcestershire sauce, and parsley.
Remove from heat and mix in the cold cooked fish and egg yolks.
Cool the mixture, then shape it into cutlets.
Fry and serve
Coat the cutlets in breadcrumbs and fry until golden brown.
Serve with Hollandaise sauce.
Make the Hollandaise
For Hollandaise, cream the butter in a bowl.
Add the egg yolks one at a time, stirring until well blended.
Stir in the lemon juice and cook over hot water until thickened.
Season with salt and cayenne pepper.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the milk into a smooth white sauce that binds the fish mixture.
- Milk
- Forms the liquid base of the sauce that holds the fish together when cooled.
- Cooked fish
- Provides the main body and flavor of the cutlets.
- Egg yolks
- Add richness and help bind the fish mixture so it holds its shape.
- Butter
- Adds richness and flavor to the sauce and the Hollandaise.
The step that matters
Adding the egg yolks to the Hollandaise. Egg yolks scramble if they get too hot too fast. Adding them one at a time and cooking gently over hot water lets them thicken smoothly into a sauce instead of curdling.
Swap the onion

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