Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Cheese Croquettes
Ingredients
Directions
Make the base
Scald the milk with the onion, then remove the onion.
Melt the butter in a pan, add the flour, and gradually pour in the milk.
Stir in the cheese and season with salt and cayenne.
Shape and coat
Spread the mixture on a plate to cool.
Shape the cooled mixture into croquettes.
Dip each croquette in breadcrumbs, then in beaten egg, and again in breadcrumbs.
Fry and drain
Fry the croquettes in deep fat until golden brown, then drain on brown paper.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the melted butter and milk into a binding mixture that holds the croquettes together.
- Butter
- Adds fat and richness and forms the roux base with the flour.
- Milk
- Provides the liquid that the flour thickens into a smooth, creamy base.
- Soft cheese
- Adds rich flavour and melts into the sauce, giving the filling its creamy body.
- Beaten egg (in the method)
- Helps the breadcrumb coating adhere and sets to form a crisp outer layer.
The step that matters
Cool the mixture fully before shaping. A warm, loose mixture cannot hold its shape and may burst or slump in the fat. Spreading it to cool lets it firm up enough to form neat croquettes that stay intact during frying.
Swap the onion
How well each one fits the dish's main ingredients (flour, milk, butter, cheese, pepper):
- Potatofits better
- Capsicumfits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against flour, milk, butter, cheese, pepper. Candidates are from the same food group and used in at least 100 recipes.
