Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onion
- Browning in the pan builds a sweet, savoury base for the sauce.
- Tomatoes
- Break down while stewing to form the body and acidity of the sauce.
- Green peppers
- Soften as they stew, adding fresh, slightly bitter flavour and texture to the sauce.
- Steak
- Provides the main protein; searing in a hot pan browns its surface for flavour.
The step that matters
Stewing the tomato and pepper sauce until thickened. Tomatoes and peppers release water as they cook. Stewing long enough lets that moisture evaporate so the sauce thickens and clings to the steak instead of running off it.
