Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Form the main protein body of the dish when poached.
- Flour
- Thickens the tomato sauce so it coats the eggs and toast.
- Tomatoes
- Provide the base and acidity of the sauce.
- Onion
- Adds savory depth to the tomato sauce.
The step that matters
Thicken the sauce with flour. Flour dissolved in water before stirring keeps it from forming lumps. Stirring until smooth lets starch gelatinize evenly, giving the sauce body without grittiness.
Swap the onion
How well each one fits the dish's main ingredients (tomato, flour, pepper, egg):
- Capsicumfits better
- Eggplantfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against tomato, flour, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
