Why it works: Pepper and tomato are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal
- Forms the main body of the dish, and browning it adds savoury flavour.
- Flour
- Coats the veal so it browns well and helps thicken the sauce.
- Cold gravy
- Forms the saucy base that the veal and ham are finished in.
- Tomato ketchup
- Adds sweetness and acidity to the sauce.
- Boiled ham
- Adds salty, savoury meat flavour to the ragout.
The step that matters
Fry the dredged veal until nicely browned. Browning the floured surface creates flavour through the Maillard reaction. If the pan is crowded or not hot enough, the veal steams instead of browning, and the sauce loses depth.
Swap the tomato
How well each one fits the dish's main ingredients (veal, butter, flour, pepper, ketchup, ham):
- Shallotfits better
- Capsicumfits better
- Leekfits better
- Tomatothe original
Fit is the average pairing score against veal, butter, flour, pepper, ketchup, ham. Candidates are from the same food group and used in at least 100 recipes.
