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 of Sweetbreads
Ingredients
Directions
Prepare the sweetbreads
Soak four veal sweetbreads in cold salted water for one hour, removing pipes and membranes.
Boil the sweetbreads in salted water with a tablespoonful of vinegar for twenty minutes.
Transfer the sweetbreads to cold water to harden.
Remove the sweetbreads, chop them very finely, almost to a paste.
Season the paste with salt, pepper, and a teaspoonful of grated onion.
Make the mixture
Add the beaten yolks of three raw eggs, one tablespoonful of butter, half a cupful of cream, and enough fine cracker crumbs to make a stiff mixture suitable for rolling into little balls or cork-shaped croquettes.
Prepare a frying kettle half full of fat over the fire.
Place a dish containing three smoothly beaten eggs and a large platter of cracker dust nearby.
Wet your hands with cold water and shape the mixture into croquettes.
Coat and fry
Roll each croquette in cracker dust, then in beaten egg, and again in cracker dust.
Smooth the outside of each croquette.
Carefully drop the croquettes into the hot fat.
Fry until a nice golden brown.
Place the fried croquettes on brown paper to drain excess grease.
Serve hot with sliced lemon or parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal sweetbreads
- Form the main body of the croquettes, giving them a soft, rich filling when chopped fine.
- Raw eggs
- Bind the chopped mixture so it holds its shape when rolled and fried.
- Cream
- Adds moisture and softness to the filling, keeping it from drying out.
- Butter
- Adds fat and richness to the filling, improving flavour and tenderness.
- Cracker crumbs (in the method)
- Give the mixture body so it can be shaped, and form a crisp, browned outer coating.
The step that matters
Coat and fry in hot fat. The egg and cracker-dust coating must be firm and evenly covered so the croquettes hold together. Fat that is hot enough browns the crust quickly and keeps the filling from absorbing grease.
Swap the onion
