Why it works: Olive and tomato 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 ↓

Directions
Prepare
Rub the steak with olive oil and lemon juice the night before.
Braise

Cover the steak with sliced onion.

Serve

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Round steak
- Forms the main body of the dish, becoming tender during long slow cooking.
- Canned tomatoes
- Add acidity and moisture, forming the sauce that braises the steak.
- Onion
- Adds sweetness and aroma as it softens into the sauce.
- Bacon fat or butter
- Adds fat for richness and helps browning in the pan.
- Lemon juice
- Adds acidity that brightens the flavor and begins to tenderize the surface.
The step that matters
Cover securely and cook slowly. Long, gentle, covered cooking lets tough connective tissue in the round steak break down into tender meat. Too much heat or an uncovered pan lets liquid evaporate and leaves the meat dry and chewy.
Swap the onion
How well each one fits the dish's main ingredients (olive, lemon, tomato, butter, pepper):
- Capsicumfits better
- Eggplantfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against olive, lemon, tomato, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
