Fry the onion until golden, then add it to the gravy.
Stir in vinegar, lemon juice, curry powder, and salt to taste.
Rub butter into enough flour to thicken the gravy properly.
Cook and serve
Cut sweetbreads into 2-inch pieces and gently stew them in the gravy until cooked through.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Provide the tender meat that is cooked gently in the curry gravy.
- Veal gravy
- Forms the liquid base that carries the flavour and body of the curry.
- Flour
- Thickens the gravy so it coats the sweetbreads rather than running thin.
- Butter
- Enriches the thickened gravy with fat and a smooth, rounded texture.
- Curry powder
- Supplies the warm spiced aroma that defines the dish.
- Onion
- Adds savoury sweetness and depth once fried golden.
The step that matters
Gently stew the sweetbreads. Sweetbreads turn firm and rubbery if boiled or stewed hard. A gentle simmer cooks the protein evenly while keeping it tender and moist.
