Anchovy Toast
Ingredients
Directions
Prepare
Prepare thin slices of buttered toast.
Spread anchovies on top of the toast.
Make the sauce and serve
In a chafing dish, melt the butter and mix in the dry mustard, tomato sauce, and mushroom sauce until smooth.
Layer the hard-boiled egg slices in the sauce and sprinkle with salt and cayenne pepper.
Heat the mixture and pour it over the anchovy toast, being careful not to break the egg slices.

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
