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 ↓
Egg Croquettes
Ingredients
Directions
Make the mixture
Boil the eggs hard, remove the shells, and pass them through a potato ricer.
Scald the milk in a double boiler, then add the melted flour and butter mixture.
Add the remaining ingredients and mix well.
Turn the mixture onto a platter to cool and let it stand for 3 hours.
Shape and fry
Shape the mixture into egg-like forms, roll in beaten egg and bread crumbs, and fry in deep fat.
Serve
Serve with well-seasoned tomato sauce and Worcestershire sauce.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide the main body and structure of the croquettes when hard-boiled and mashed.
- Milk
- Forms the moist base that binds the mashed eggs into a soft, spreadable mixture.
- Flour
- Thickens the milk with the butter, giving the mixture body so it holds its shape.
- Butter
- Adds richness and fat, softening texture and carrying flavour through the mixture.
The step that matters
Letting the mixture stand and cool. The mixture must cool and set firmly before shaping; if it is still warm and soft, the forms will slump and may split or burst during frying.
Swap the onion
How well each one fits the dish's main ingredients (egg, parsley, milk, butter, flour, pepper):

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