What each ingredient does

Bread: Provides a crisp, toasted base that holds the butter and anchovies.
Anchovy fillets: Add salty, savoury depth that stands out against the rich butter.
Butter: Adds fat and richness, carrying flavour across the toast.
Lemon juice: Adds acidity that brightens the rich butter and salty anchovies.
