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 ↓
Macaroni Croquettes
Ingredients
Directions
Make the filling
Combine macaroni, chopped ham or tongue, grated cheese, salt, and pepper in a bowl.
Heat milk in a saucepan and whisk in flour and butter until thickened.
Add the milk mixture to the meat and cheese mixture.
Spread the mixture on a plate and let cool.
Shape and coat
Once cool, form the mixture into croquettes.
Mix the beaten egg with cold water and reserved cheese in a shallow dish.
Dip each croquette in the egg mixture.
Fry and serve
Fry the croquettes until golden brown.
Serve with tomato sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Forms the bulk of the croquette, giving it body and a soft, starchy filling.
- Ham or tongue
- Adds savoury meat flavour and firmness to the filling.
- Cheese
- Melts into the filling for richness and binds it, and adds flavour to the coating.
- Milk
- With flour and butter, forms a thickened white sauce that holds the filling together.
- Flour
- Thickens the milk mixture so the filling sets firm enough to shape.
- Egg
- Coats the croquettes so the outer layer holds together and browns when fried.
The step that matters
Let the filling cool fully before shaping. A warm, soft filling is too loose to hold its shape and can burst or fall apart in the hot oil. Cooling lets the starch in the thickened sauce set, so the croquettes stay firm and intact while frying.
Swap the tomato
How well each one fits the dish's main ingredients (ham, cheese, pepper, milk, flour, butter, egg):
