Why it works: Onion and butter are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 42,912 recipes. Both carry decanal, which smells soap, orange peel. The science ↓
Curried Sweetbreads
Ingredients
Directions
Prepare the sweetbreads
Wash and soak the sweetbreads.
Place them in boiling water with a little coarse sea salt and a whole onion.
Simmer for 10 minutes. Alternatively, use weak veal broth instead of water.
Remove the sweetbreads.
Let them cool completely on a drain.
Cut the cooled sweetbreads into half-inch slices.
Optionally, flour the slices.
Cook and serve
Lightly fry the slices in butter. Alternatively, place them in enough curried gravy to cover.
Stew the sweetbreads gently in the gravy for 20 to 30 minutes.
Stew 1 ounce of freshly grated cocoa nut in the gravy before adding the sweetbreads.
Add lemon juice to taste before serving hot. Alternatively, add chili vinegar to taste before serving 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, delicate meat that forms the body of the dish.
- Butter
- Adds richness and browning when the slices are lightly fried.
- Curried gravy
- Supplies the moisture and spiced sauce in which the sweetbreads are stewed.
The step that matters
Stewing the sweetbreads gently in the gravy. Gentle heat keeps the delicate sweetbread tender and prevents it from toughening or breaking apart, as vigorous boiling would do.
Swap the cocoa
The recipe marks cocoa as optional. How well each one fits the dish's main ingredients (onion, butter, lemon):
- Sesamefits better
- Chickpeafits better
- Pistachiofits better
- Cocoathe original
Fit is the average pairing score against onion, butter, lemon. Candidates are from the same food group and used in at least 100 recipes.
