Why it works: Butter and milk 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
In a saucepan, melt the butter over medium heat.
Stir in the flour to make a roux, then gradually add the milk, stirring until thickened.
Remove from heat and stir in the egg yolks without beating.
Add the grated cheese and stir until melted, then season with salt, pepper, and cayenne.
Spread the mixture in a shallow pan and let it cool.
Shape and fry
Once cooled, turn it out onto a board and cut into small squares or strips.
Dip each piece in breadcrumbs, then in beaten egg, and again in breadcrumbs.
Fry in deep fat until golden brown and drain on paper towels.
Serve
Serve as a cheese course or as a dish for lunch or supper.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the roux and adds richness and a nutty flavour to the base.
- Flour
- Forms a roux with the butter that thickens the milk into a smooth sauce.
- Milk
- Liquid that, with the flour, becomes a thick sauce to bind the cheese.
- Mild cheese
- Provides the main flavour and, once melted, the creamy body of the filling.
- Egg yolks
- Add richness and help bind the mixture as it cools and sets.
The step that matters
Let the mixture cool fully before shaping. The mixture must be cold and firm to hold its shape. If it is warm or soft, the pieces lose their form and can break or leak in the hot fat, so the cheese base should set completely first.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
