Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Rissoles of Sweetbreads
Ingredients
Directions
Prepare the sweetbreads
Boil the sweetbreads for 1 hour until tender. Let them cool and chop finely.
Make the filling
In a saucepan, combine minced veal, mushrooms, ketchup, and butter. Stir to prevent burning.
Dredge in flour, then add broth and cream. Stir until it boils and thickens.
Strain the mixture and use some to moisten the chopped sweetbreads. Boil for 3-4 minutes.
Shape and fry
When cool, form the mixture into small balls and roll in bread crumbs.
Dip the balls in beaten egg, then roll in bread crumbs again. Refrigerate until needed.
Fry the balls in boiling lard until golden. Serve in a napkin with sauce on the side.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calves’ sweetbreads
- Provide the tender, rich meat that forms the body of the filling.
- Minced veal
- Adds meaty bulk and structure to the filling.
- Flour
- Thickens the sauce so the mixture holds together when shaped.
- Cream
- Adds richness and smoothness to the thickened sauce.
- Egg
- Binds the coating so the bread crumbs adhere during frying.
- Bread crumbs
- Form a crisp outer crust that browns when fried.
The step that matters
Thickening the sauce before shaping. The mixture must boil and thicken fully after the flour is added. If it stays thin, the balls will not hold their shape and may break apart in the coating or the hot lard.
