Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Chicken Croquettes
Ingredients
Directions
Make the filling
Boil the cream or chicken stock in a saucepan.
In a separate bowl, mix the flour and butter, then stir into the boiling cream.
Add the chopped chicken, salt, pepper, onion juice, and lemon juice; boil for 2 minutes.
Remove from heat and stir in 2 beaten eggs; let cool.
Shape and fry
Once cool, shape the mixture into croquettes.
Roll each croquette in the remaining beaten egg and breadcrumbs.
Fry in hot oil until golden brown.

Flour and butter 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
- Chicken
- Forms the bulk of the filling and gives the croquettes their main texture.
- Flour
- Thickens the cream so the filling becomes firm enough to shape.
- Eggs
- Bind the filling and set when cooked, helping the croquettes hold together.
- Butter
- Adds fat for richness and a smoother, more tender filling.
- Breadcrumbs
- Form a crisp coating that browns during frying.
- Lemon juice
- Adds acidity that brightens the flavour of the rich filling.
The step that matters
Stir in the eggs off the heat, then let the mixture cool fully. Adding eggs to a very hot mixture can scramble them and leave lumps. Cooling lets the filling firm up, so the croquettes keep their shape when rolled and fried.
Swap the onion
How well each one fits the dish's main ingredients (chicken, pepper, cream, flour, egg, lemon, butter):
- Spinachfits better
- Asparagusfits better
- Leekfits better
- Onionthe original
Fit is the average pairing score against chicken, pepper, cream, flour, egg, lemon, butter. Candidates are from the same food group and used in at least 100 recipes.
