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 ↓
Chicken Croquettes
Ingredients
Directions
Make the filling
In a bowl, combine chicken, sweetbreads, salt, pepper, and nutmeg.
In a saucepan, heat milk and beat in egg yolk, cooking until slightly thickened.
Stir in butter and flour, cooking until the mixture is ropy.
Mix the chicken into the gravy and let it cool, adjusting consistency as needed.
Shape and fry
Once cool, shape the mixture into croquettes.
Dip each croquette in egg white, then coat with crushed crackers.
Fry in hot lard until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chicken
- Forms the bulk of the filling, giving the croquettes body and savory flavor.
- Milk
- Forms the base of the gravy, providing moisture for a smooth, creamy filling.
- Egg yolk
- Thickens the milk as it cooks and adds richness to the filling.
- All-purpose flour
- Thickens the gravy with butter, helping the filling hold its shape when cooled.
- Egg white
- Acts as a binder so the cracker crumbs adhere to the shaped croquettes.
The step that matters
Cooling the filling before shaping. The gravy must cool and firm up enough to hold its shape; shaping a warm, loose mixture makes croquettes slump and burst during frying.
Swap the nutmeg
How well each one fits the dish's main ingredients (chicken, pepper, milk, egg, butter, flour):
- Nutmegthe original
- Parsleyfits about as well
- Cinnamonfits about as well
- Tarragonfits about as well
Fit is the average pairing score against chicken, pepper, milk, egg, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
