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 ↓
Sauce for Croquette Mixture
Ingredients
Directions
Make the sauce
Scald the milk, cream, or stock in a double boiler.
Melt the butter in a saucepan.
Stir in the flour, salt, pepper, and nutmeg until smooth.
Add the smooth mixture to the scalded milk gradually, stirring frequently.
Cook for 10 minutes, stirring often.
Shape and coat
Add the sauce to the chopped mixture gradually to avoid making it too thin.
Mould the mixture into shape.
Dip the shaped mixture in breadcrumbs.
Dip the breadcrumb-coated mixture in beaten egg.
Dip the egg-coated mixture in breadcrumbs again.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk, cream, or stock
- Forms the liquid base of the sauce that thickens into a smooth, creamy binder.
- Butter
- Adds fat and richness and cooks with the flour to form the thickening roux.
- Flour
- Thickens the liquid as its starch swells with heat, giving the sauce body.
The step that matters
Adding the flour mixture to the scalded liquid. Adding the roux gradually and stirring frequently keeps it smooth, because flour clumps when it meets hot liquid all at once. Adding sauce gradually to the chopped mixture also prevents it from becoming too thin.
Swap the nutmeg
The recipe marks nutmeg as optional. How well each one fits the dish's main ingredients (milk, butter, flour, pepper):
- Cinnamonfits about as well
- Nutmegthe original
- Cardamomfits about as well
- Parsleyfits about as well
Fit is the average pairing score against milk, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
