Why it works: Potato and pepper are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 8,305 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rump steak
- Provides the main protein; broiling over high heat browns its surface while keeping the inside tender.
- Potatoes
- Frying in hot butter browns their surface and gives a crisp exterior with a soft interior.
- Butter
- Carries heat for frying the potatoes and adds rich flavor and browning, then is poured over the steak.
The step that matters
Fry the potatoes in the hot butter until nicely browned. Butter that is not hot enough will steam the thin potato slices instead of browning them, leaving them pale and greasy. Frying in properly heated fat drives off surface moisture so the slices crisp.
Swap the potato
How well each one fits the dish's main ingredients (butter, pepper):
- Capsicumfits better
- Potatothe original
- Carrotfits less well
- Onionfits less well
Fit is the average pairing score against butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
