Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Break down into the body and liquid of the sauce.
- Eggs
- Set into soft, tender pieces that enrich the tomato sauce when poached in it.
- Sugar
- Balances the acidity of the tomatoes, adding sweetness.
The step that matters
Poach the eggs in the boiling tomato sauce. Eggs set through gently at a steady simmer; at a hard boil the whites can turn rubbery and tear apart, while the yolks may overcook. Cooking them separately and adding them to the sauce gives more control.
Swap the tomato
How well each one fits the dish's main ingredients (sugar, pepper, egg):
- Capsicumfits better
- Asparagusfits better
- Sweet potatofits better
- Tomatothe original
Fit is the average pairing score against sugar, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
