Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set when cooked, giving the filling its body and binding it together.
- Butter
- Adds richness and a soft, smooth texture to the cooked egg.
- Tomato pulp
- Adds moisture and bright, slightly acidic tomato flavour to the filling.
The step that matters
Cook the mixture as you would for scrambled eggs. Cooking gently over low heat and stopping while the eggs are still soft keeps the filling creamy. High heat or overcooking makes the egg firm and dry, and excess liquid from the tomato can make it watery.
Swap the tomato
How well each one fits the dish's main ingredients (egg, pepper, butter, bread):
- Capsicumfits better
- Asparagusfits better
- Chivefits about as well
- Tomatothe original
Fit is the average pairing score against egg, pepper, butter, bread. Candidates are from the same food group and used in at least 100 recipes.
