Why it works: Bread and tomato are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 1,013 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Calf's Sweetbreads
Ingredients
Directions
Prepare
Soak sweetbreads in cold salt water for some time.
Parboil the sweetbreads and then place them in cold water.
Once cold, carefully trim the sweetbreads.
Cook and serve
Fry the sweetbreads in egg and bread crumbs until golden brown.
Alternatively, bake the sweetbreads in the oven, basting them well.
If not breaded and not brown, pour thick white sauce over them.
If fried to a nice brown, serve with sauce around them.
Tomato sauce, brown gravy, or curry sauce can also be used.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- The main protein, whose tender texture is the centre of the dish.
- Egg
- Binds the bread crumbs to the sweetbreads so the coating holds during frying.
- Bread crumbs
- Form a crisp coating that browns during frying.
- Thick white sauce (such as bechamel)
- Adds moisture and richness to sweetbreads that are not breaded or browned.
The step that matters
Parboil the sweetbreads and chill them before trimming. Parboiling firms the delicate membranes so they can be trimmed cleanly, and cooling stops the cooking so the texture stays tender rather than becoming rubbery.
Swap the tomato
How well each one fits the dish's main ingredients (egg, bread, sauce):
- Shallotfits about as well
- Asparagusfits about as well
- Capsicumfits about as well
- Tomatothe original
Fit is the average pairing score against egg, bread, sauce. Candidates are from the same food group and used in at least 100 recipes.
