Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled eggs
- Provide the main body and protein of the filling, which is warmed through in the sauce.
- Butter
- Adds richness and fat, carrying flavour through the warm sauce.
- Worcestershire sauce
- Adds savoury, tangy depth and salt-like umami to the filling.
- Mushroom ketchup
- Contributes concentrated savoury umami flavour to the filling.
- Anchovy paste
- Adds a salty, savoury umami base under the egg topping.
The step that matters
Heat the mixture thoroughly. Eggs and the sauce need to be heated evenly all the way through so the filling is hot and well blended. Gentle, even heat over medium prevents the butter and sauce from scorching while the eggs warm, and keeps the slices from breaking down into a rough, uneven mash.
Swap the mustard
How well each one fits the dish's main ingredients (butter, tomato, sauce, mushroom, ketchup, egg, pepper):
- Capsicumfits better
