Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

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 in butter gives it savory flavor.
- Flour
- Dredging coats the veal, and the smoothly-mixed flour thickens the pan liquid into a sauce.
- Butter
- Fat for frying that browns the veal and adds richness to the pan sauce.
- Onion
- Adds aromatic sweetness and savory depth to the sauce as it fries with the veal.
- Catsup
- Adds sweetness, acidity and tomato flavor to the sauce.
- Lemon juice
- Adds acidity that brightens the sauce and balances its richness.
The step that matters
Return the veal to the pan and heat until very hot. The veal is already cooked and cold, so it only needs to warm through. Overheating can toughen the meat and cause the thickened sauce to break or become stringy, so heat just until steaming hot and serve promptly.
Swap the onion
How well each one fits the dish's main ingredients (veal, flour, butter, pepper, lemon):
- Shallotfits better
- Leekfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against veal, flour, butter, pepper, lemon. Candidates are from the same food group and used in at least 100 recipes.
