Why it works: Onion and celery are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 18,518 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Chicken Croquettes
Ingredients
Directions
Make the filling
Parboil and mash the sweetbreads.
Boil the sweetbreads in cream with butter, onion, celery, white pepper, and nutmeg.
Strain the mixture and thicken with flour.
Add chopped chicken or turkey until the mixture is not too stiff and let it cool.
Shape and coat
Beat the egg and add a little milk.
Form the mixture into croquettes, roll in crumbs, then in egg, and again in crumbs.
Set aside in a cool place.
Fry
Fry a few croquettes at a time 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
- Sweetbreads
- Provide the soft, tender body of the filling after parboiling and mashing.
- Cream
- Adds richness and moisture to the filling as it boils with the sweetbreads.
- Flour
- Thickens the strained mixture so it holds its shape when formed.
- Chopped chicken or turkey
- Supplies the main meat flavor and bulk of the croquette filling.
- Egg
- Acts as a binder for the crumb coating, helping crumbs adhere before frying.
- Bread crumbs
- Form a crisp, golden outer crust when fried in hot lard.
The step that matters
Let the mixture cool until it is not too stiff, then shape before frying. Flour thickens the filling as it cools, and a filling that is too stiff or too warm will crack or slump. Chilling firms it so the croquettes hold their shape through breading and frying.
Swap the white pepper
How well each one fits the dish's main ingredients (cream, egg, butter, onion, celery, nutmeg, flour):
- Parsleyfits better
- Cinnamonfits better
- Tarragonfits better
- White pepperthe original
Fit is the average pairing score against cream, egg, butter, onion, celery, nutmeg, flour. Candidates are from the same food group and used in at least 100 recipes.
