Why it works: Bread and butter 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 ↓
Veal Sweetbreads Roasted
Ingredients
Directions
Prepare
Boil the sweetbreads in a stewpan of water with a little coarse sea salt for a few minutes.
Remove the sweetbreads and place them in a basin of cold water until cool.
Beat the egg in a dish.
Roast
Skewer the sweetbreads and fasten them on the spit.
Brush the sweetbreads with the beaten egg.
Sprinkle the sweetbreads with bread crumbs.
Drizzle clarified butter over the sweetbreads.
Add more bread crumbs to the sweetbreads.
Roast for 15 minutes.
Serve
Remove the sweetbreads from the skewer and serve on a dish with hot butter sauce mixed with gravy, a small bit of glaze, and a squeeze of lemon juice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Heart sweetbreads
- Main protein; boiling firms them so they hold their shape while roasting.
- Egg
- Beaten egg acts as a binder so the bread crumbs adhere to the sweetbreads.
- Bread crumbs
- Form a crisp, golden coating during roasting through browning.
- Clarified butter
- Fat that conducts heat for even browning and adds richness to the crust.
The step that matters
Cooling the boiled sweetbreads. Placing the sweetbreads in cold water after boiling stops the cooking so they stay tender rather than overcooked and firm. Thorough cooling also makes them easier to handle before skewering and coating.
