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 sauce
Melt the butter in a pan.
Add the flour and cheese, stirring until well blended.
Gradually add the milk and onion juice, then season with salt and pepper.
Shape and fry
Allow the mixture to cool, then fold in the cooked macaroni.
Shape the mixture into croquettes, then dip in breadcrumbs, beaten egg, and more breadcrumbs.
Fry the croquettes in deep fat until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the flour base and adds richness and flavour to the sauce.
- Flour
- Thickens the butter and milk into a sauce that holds the croquettes together.
- Milk or stock
- Liquid that turns the flour and butter into a smooth, thick sauce.
- Cheese
- Adds savoury flavour and helps the sauce bind and set.
- Cooked macaroni
- Provides the bulk and body of the croquette filling.
The step that matters
Allow the mixture to cool before shaping. A warm, loose sauce cannot hold its shape and may burst or leak during frying. Cooling lets the starch set the sauce firm enough to form and coat neatly.
Swap the onion
How well each one fits the dish's main ingredients (milk, butter, flour, pepper, cheese):
- Potatofits better
- Capsicumfits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against milk, butter, flour, pepper, cheese. Candidates are from the same food group and used in at least 100 recipes.
