Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Stewed Steak

Directions

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Steak
- Forms the main body of the dish, becoming tender as it stews.
- Onions
- Soften during stewing, adding sweetness and body to the gravy.
- Flour
- Thickens the gravy as the butter-flour mixture is stirred in.
- Ketchup
- Adds acidity and sweetness that give the gravy depth of flavour.
The step that matters
Let it stew slowly under a cover. Gentle, covered heat lets the connective tissue in the steak break down slowly, so the meat turns tender without drying out. Rapid boiling toughens the meat and can scorch the liquid.
Swap the onion
How well each one fits the dish's main ingredients (ketchup, pepper, butter, flour):
- Capsicumfits better
- Shallotfits better
- Turnipfits better
- Onionthe original
Fit is the average pairing score against ketchup, pepper, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
