Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Round steak
- Main cut that becomes tender during slow, covered cooking in liquid.
- Flour
- Coats the steak so it browns well and helps thicken the sauce.
- Tomatoes
- Provide acidity and liquid that gently braise the meat.
- Onion
- Adds sweetness and savory depth as it softens into the sauce.
The step that matters
Cook slowly for 2 to 3 hours. Low, covered heat breaks down the tough connective tissue in round steak into gelatin, making the meat tender. Rushing with high heat leaves it tough and dry.
Swap the onion
How well each one fits the dish's main ingredients (flour, meat, tomato, pepper):
- Capsicumfits better
- Okrafits better
- Eggplantfits better
- Onionthe original
Fit is the average pairing score against flour, meat, tomato, pepper. Candidates are from the same food group and used in at least 100 recipes.
