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
Chop the boiled chicken and calf’s brains very finely.
In a saucepan, melt the butter over medium heat.
Add the minced onion and parsley, then stir in a little flour.
Thin the mixture with beef stock until smooth.
Add pepper, salt, lemon juice, and sherry or port wine.
Shape and fry
Mould the mixture into shapes, dip in beaten egg, then coat with cracker crumbs.
Fry in boiling 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
- Boiled chicken
- Forms the bulk of the filling and gives the croquettes their main body.
- Calf’s brains
- Adds richness and a soft, creamy texture to the filling.
- Butter
- Adds fat and flavour to the base where the flour is cooked in.
- Flour
- Thickens the mixture so it holds its shape when moulded.
- Egg
- Binds the coating so the cracker crumbs adhere before frying.
- Cracker crumbs
- Forms a crisp, golden outer layer when fried.
The step that matters
Thin the mixture with beef stock until smooth. The flour thickens the filling as it is added, so the stock must be stirred in gradually to avoid lumps. A smooth, properly thickened filling is firm enough to mould and hold its shape during frying.
Swap the onion
How well each one fits the dish's main ingredients (chicken, parsley, butter, flour, beef, pepper, lemon):
- Shallotfits better
- Potatofits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against chicken, parsley, butter, flour, beef, pepper, lemon. Candidates are from the same food group and used in at least 100 recipes.
