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 cheese base
Heat the milk in a saucepan.
Mix the flour with a little cold milk to form a paste, then stir it into the hot milk.
Add the butter and mix well, then remove from heat.
Beat the egg lightly and add it to the mixture along with salt, black pepper, cayenne, and mustard. Mix thoroughly.
Stir in the grated cheeses until well combined.
Chill the mixture in the refrigerator.
Shape and coat
Form the mixture into croquettes.
Dip each croquette in beaten egg and then in bread crumbs.
Return the croquettes to the refrigerator for several hours.
Fry and serve
Fry the croquettes in deep, hot oil until golden brown and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base of the white sauce that binds the croquette mixture.
- Flour
- Thickens the milk into a paste-like sauce that gives the croquettes body and structure.
- Butter
- Adds richness and fat that makes the sauce smooth and tender.
- Egg
- Binds the mixture and helps it set firm when cooked.
- Gruyere cheese
- Melts into the sauce to add savory, nutty flavor and creaminess.
- American cheese
- Adds meltiness and extra creaminess to the filling.
The step that matters
Chill the croquettes thoroughly before frying. Chilling firms the cheese sauce so the croquettes hold their shape. If they are still soft, they can burst or leak cheese into the hot oil.
Swap the mustard
How well each one fits the dish's main ingredients (milk, flour, walnut, butter, pepper, egg, gruyere cheese):
