Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Chicken Croquettes
Ingredients
Directions
Make the filling
In a saucepan, blend flour and butter over low heat.
Add cream and season with onion juice, parsley, lemon juice, salt, and cayenne.
Cook until the sauce thickens, then stir in the chopped chicken and heat through.
Shape and coat
Once cool, form the mixture into croquettes.
Coat each croquette in cracker dust, then dip in beaten egg, and coat again in cracker dust.
Fry
Fry in hot lard until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the butter and cream into a sauce that binds the chicken together.
- Butter
- Adds fat and richness to the sauce and carries the flour's thickening.
- Cream
- Makes the sauce smooth and moist so the filling stays tender.
- Cooked chicken
- Forms the main body of the croquettes, providing protein and bulk.
- Beaten egg
- Binds the cracker dust coating so it adheres and forms a crisp shell.
The step that matters
Cook the sauce until it thickens before adding the chicken. If the flour and butter roux and cream are not cooked until thick, the sauce stays thin and the mixture will not hold its shape when formed and fried.
Swap the onion
How well each one fits the dish's main ingredients (chicken, flour, butter, cream, parsley, lemon, egg):
- Leekfits better

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