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
Wash and soak the sweetbreads, then place them in boiling water with a little coarse sea salt and a whole onion.
Simmer for 10 minutes, or use weak veal broth instead of water.
Remove the sweetbreads and let them cool completely on a drainer.
Cut the cooled sweetbreads into half-inch slices.
Optionally, flour and lightly fry the slices in butter, or place them in enough curried gravy to cover.
Stew the sweetbreads gently in the gravy for 20 to 30 minutes.
Add lemon juice or chili vinegar to taste before serving hot.
For added flavor, stew 1 ounce of freshly grated cocoa nut in the gravy before adding the sweetbreads.
