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

What each ingredient does

Anchovies
Provide a salty, savoury flavour that stands out against the sauce and egg.
Butter
Melts into the sauce, adding richness and a smooth texture.
Hard-boiled eggs
Add a soft, creamy texture and mild richness to the topping.
Tomato sauce
Adds sweetness and acidity to the sauce, giving it body and colour.
Dry mustard
Adds a sharp, pungent bite that balances the richness of the butter and eggs.

The step that matters

Heating and pouring the sauce over the toast. Heating the sauce gently keeps the butter emulsified and the sauce smooth, while careful pouring keeps the delicate egg slices intact on the toast.

Swap the mustard
