Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leeks
- Main vegetable; softened by scalding and frying, then braised until tender in the sauce.
- Olives
- Add salty, briny flavour and a savoury depth to the sauce.
- Tomato sauce
- Provides acidity and body, forming the liquid that reduces during baking.
- Vinegar
- Adds sharpness that balances the sweetness and richness of the oil.
- Sugar
- Adds a touch of sweetness that rounds out the sharp and salty flavours.
The step that matters
Bake until the liquid is reduced. Baking long enough lets the liquid thicken into a concentrated sauce that coats the leeks. Stopping too early leaves the dish watery and the flavours diluted.
Swap the leek
How well each one fits the dish's main ingredients (sugar, vinegar, tomato, sauce, olive, pepper):
- Capsicumfits better
