Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Provide the main protein, which becomes tender when gently stewed in the gravy.
- Veal gravy
- Forms the liquid base that carries the flavour and moisture of the dish.
- Butter
- Combined with flour to make a roux that thickens the gravy and adds richness.
- Flour
- Thickens the gravy when worked with butter, giving it body.
- Curry powder
- Supplies the dominant spiced aroma and flavour of the dish.
- Onion
- Adds sweetness and savoury depth when fried golden before going into the gravy.
The step that matters
Stew the sweetbreads gently until cooked through. Sweetbreads are delicate; a hard boil toughens and dries the proteins, so they should simmer gently in the gravy until firm and cooked through.
