Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Olive oil
- Carries the heat and flavor of the aromatics and helps the onion brown evenly.
- Onion
- Sweetens and builds the savory base of the sauce as it turns golden.
- Plum tomatoes
- Provide the liquid and acidity that form the body of the sauce.
- Anchovy
- Melts into the sauce to add deep savory flavor without tasting distinctly fishy.
- Olives
- Add salty, briny flavor and a meaty texture to the sauce.
- Capers
- Add sharp, salty bursts of acidity that cut through the rich tomato base.
The step that matters
Sauté the onion until golden. Cooking the onion until golden browns its sugars, giving the sauce sweetness and depth. Pale, underdone onion leaves the sauce tasting flat and sharp.
