Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Set into soft curds that form the body of the dish.
Strained tomatoes
Provide moisture and a bright, acidic tomato flavour.
Butter
Adds richness and fat that carries flavour and keeps the eggs tender.
Grated onion
Adds savoury aroma and depth to the tomato base.

The step that matters

Cook the eggs, breaking them into large curds as they cook. Egg proteins set with heat, and cooking them too hot or too long makes them tough and watery. Removing the pan from heat when the eggs are still slightly glossy lets residual heat finish them gently.

Swap the white pepper

How well each one fits the dish's main ingredients (butter, onion, tomato, sugar, egg):
