Anchovy Sandwiches
Ingredients
Directions
Prepare the anchovy filling
Pound the anchovies in a mortar with the butter and minced olives.
Spread the mixture on thin slices of bread.
Cover with another buttered slice and cut into oblongs.
Alternatively, bone the anchovies and cut into small fillets.
Make the egg sandwich
Pound the yolks of the hard-boiled eggs with cayenne and vinegar.
Spread the egg mixture on buttered bread, sprinkle with minced whites, and layer with filleted anchovies.
Top with chopped mustard and cress, then cover with another slice of buttered bread.

- Provide the salty, savoury flavour that is the main taste of the sandwich.
- Butter
- Adds fat and richness and helps bind the pounded filling to the bread.
- Hard-boiled egg yolks
- Form a smooth, creamy spread that gives the sandwich its body.
- Olives
- Add a briny, savoury note that complements the anchovies.
- Vinegar
- Adds acidity that brightens the rich egg and butter mixture.
