Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Croquettes
Ingredients
Directions
Prepare the filling
Cook the chicken and sweetbreads until done.
Mince the chicken and sweetbreads as fine as possible.
Chop the onion finely and add it to the minced mixture.
Season with salt and pepper.
Melt the butter, then mix it with the cream and flour, and bring to a boil.
Stir in the minced chicken and sweetbreads, then let it cool.
Shape and coat
Shape the mixture into croquettes and roll them in powdered cracker.
Chill the croquettes in the refrigerator until ready to fry.
Before frying, roll each croquette in a beaten yolk of egg and then in cracker crumbs.
Fry
Fry in hot lard until golden brown.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Chicken
- Provides the main body of the filling once cooked and finely minced.
- Sweetbreads
- Add a soft, tender texture and rich flavor to the minced filling.
- Flour
- Thickens the cream with butter so the mixture holds its shape for shaping.
- Cream
- Adds moisture and richness, binding the filling into a smooth mixture.
- Yolk of egg
- Binds the outer coating so the cracker crumbs stick to each croquette.
The step that matters
Chill the croquettes before frying. Chilling firms the fat and starch in the filling so the croquettes keep their shape and do not burst or spread in hot lard.
Swap the onion
How well each one fits the dish's main ingredients (chicken, flour, butter, cream, pepper, egg):
- Potatofits better
- Leekfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against chicken, flour, butter, cream, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
