In a pan, melt the butter, then stir in the flour until smooth.

Fry

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Meat
- Forms the bulk of the filling and provides the savory flavor.
- Flour
- Thickens the butter and milk sauce that binds the meat mixture together.
- Butter
- Fat that is melted with flour to form the base of the sauce.
- Milk
- Liquid that, with the flour and butter, makes a thick sauce adding moisture and richness.
- Egg
- Coats the shaped croquettes so the cracker crumbs adhere and help them hold their shape.
The step that matters
Let the mixture cool before shaping. The sauce must firm up once cooled; if the mixture is still warm and loose, the croquettes will not hold their shape and may break apart in the hot fat.
Swap the onion
How well each one fits the dish's main ingredients (meat, parsley, flour, butter, milk, egg):

Fit is the average pairing score against meat, parsley, flour, butter, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
