Why it works: Tomato and olive are a kitchen classic. They rank in the top 1% of all ingredient pairs, and cooks put them together in 15,539 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Provide the tender, rich meat that forms the body of the croquettes.
- Cornstarch
- Thickens the mixture so it sets firm enough to cut and coat.
- Cream
- Adds richness and smoothness to the filling, softening its texture.
- Eggs
- Bind the coating so bread crumbs stick to the pieces.
- Bread crumbs
- Form a crisp, golden outer crust when fried.
- Tomatoes
- Add moisture and gentle acidity to the filling.
The step that matters
Cooling the mixture before cutting. The filling must cool and firm after thickening; cutting it warm causes it to slump and makes the pieces hard to coat and fry cleanly.
Swap the onion
How well each one fits the dish's main ingredients (vinegar, cream, chicken, tomato, olive, mushroom, egg):
- Capsicumfits better
- Spinachfits about as well
- Potatofits about as well
- Onionthe original
Fit is the average pairing score against vinegar, cream, chicken, tomato, olive, mushroom, egg. Candidates are from the same food group and used in at least 100 recipes.
