Why it works: Butter and mushroom are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 12,525 recipes. Both carry trans-2-decenal, which smells waxy, orange. The science ↓
Prussian Cutlets
twelve croquettesIngredients
Directions
Prepare the filling
Boil the sweetbreads and tongue, then dice them together with the mushrooms.
Make a white sauce by combining the broth, butter, and flour; boil it down to half its original quantity.
Flavor the sauce with lemon juice and salt, then dissolve the gelatin and add it to the sauce along with the Madeira and egg yolks.
Mix in the diced sweetbreads, tongue, and mushrooms to form a paste.
Set and shape
Spread the mixture over a dish that has breadcrumbs scattered on it, then top with another layer of breadcrumbs.
Let it stand in a cool place for an hour.
Form the mixture into twelve croquettes, rolling them in flour, egg, and breadcrumbs.
Fry and serve
Fry the croquettes in butter or dripping until golden.
Wash and dry some parsley, fry it for half a minute, and use it to garnish the croquettes.
Serve the croquettes in a serviette.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbread
- Provides the soft, tender meat that forms the bulk of the filling.
- Gelatine
- Helps the filling set firm so it can be shaped into croquettes.
- Egg yolks
- Enrich and bind the sauce, adding richness and helping it hold together.
- Flour
- Thickens the broth and butter into a white sauce that binds the filling.
- Butter
- Adds richness to the white sauce and fat for frying the croquettes golden.
- Mushrooms
- Add earthy flavor and moisture to the diced filling.
The step that matters
Let the mixture stand in a cool place for an hour. The gelatine and starch-thickened sauce must set firmly before shaping, otherwise the croquettes will be soft and may fall apart when rolled and fried.
