Why it works: Carrot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Baked Sweetbreads
Ingredients
Directions
The book says “a hot oven”. The 400°F in the steps is the modern equivalent, not the book's own figure.
Prepare
Place sweetbreads in a pot with cold water, salt, and vinegar.
Bring the pot to a boil, then remove the pot from heat.
Transfer the sweetbreads to cold water until cool.
Bake
Lard sweetbreads with lardoons.
Layer pork trimmings in a baking dish, then place sweetbreads on top.
Sprinkle chopped vegetables over them.
Bake in a hot oven (400°F / 200°C) for 20 minutes.
Serve
Fry the shaped bread slice in hot butter until golden.
Place the crouton in the center of a hot platter.
Arrange sweetbreads on top.
Serve with peas or tomato sauce around.

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 main body of the dish.
- Lardoons
- Add fat that bastes the sweetbreads and keeps them moist as they bake.
- Pork trimmings
- Release fat and flavor into the dish as they cook under the sweetbreads.
- Bread slice
- Forms a golden fried base that soaks up juices and gives the dish a crisp contrast.
- Butter
- Browns in the pan to add nutty aroma and golden color to the bread.
The step that matters
Cooling the sweetbreads after boiling. Moving the sweetbreads into cold water stops residual cooking, so they firm up and keep a smooth, tender texture rather than turning tough and grainy.
Swap the onion

Fit is the average pairing score against vinegar, carrot, celery, parsley, pork, bread, butter. Candidates are from the same food group and used in at least 100 recipes.
