Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Strained tomatoes
- Cook down to form the thick base of the sauce.
- Brown sauce
- Adds savory depth and body to the tomato puree.
- Eggs
- Provide the soft, runny poached centerpiece once cooked.
- Finely minced onion
- Adds aromatic sweetness and flavor to the tomato base as it stews.
The step that matters
Stewing the tomato and onion until thick. Tomatoes contain a lot of water, so they must reduce fully to a thick puree; otherwise the sauce will be thin and run around the poached egg.
Swap the onion
How well each one fits the dish's main ingredients (tomato, sauce, pepper, vinegar, capers, egg):
- Mustardfits better
