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 ↓
Veal Sweetbread
Ingredients
Directions
Prepare the sweetbread
Trim the sweetbread and parboil it for 5 minutes.
Transfer it to a basin of cold water until cool.
Dry the sweetbread thoroughly with a cloth.
Run a skewer through the sweetbread.
Brush it with egg and coat it well with bread crumbs.
Roast and make the sauce
Roast the sweetbread until golden.
In a frying pan, melt butter and mix with browned flour to create a roux.
Gradually thin the roux with boiling water and lemon juice.
Add minced pickle and curry powder mixed with cold water.
Serve
Boil the sauce sharply and pour it over the roasted sweetbread.
Let it stand covered for 10 minutes before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbread
- Main protein; its delicate, tender texture is the centre of the dish.
- Butter
- Fat that combines with browned flour to form the roux and carries flavour into the sauce.
- Browned flour
- Thickens the sauce and adds a toasted, nutty colour and flavour.
- Bread crumbs
- Form a crisp golden crust on the outside of the sweetbread when roasted.
- Lemon juice
- Adds acidity that brightens the rich, buttery sauce.
- Curry powder
- Adds warm spice aroma and flavour to the sauce.
The step that matters
Drying and roasting the coated sweetbread. Moisture left on the sweetbread keeps bread crumbs from adhering and steams the crust instead of browning it. Thorough drying before crumbing lets the surface crisp and turn golden in the oven.
