This is my version of a recipe from 'Book of Afternoon Tea' by Marika Hanbury Tenison.
List of Ingredients
Tin of Sardines
Soft Butter
Bread, sliced thin and crusts removed
Instructions
Drain and mash sardines. Butter the bread and spread with the mashed sardines. Cover with another slice of bread and press down firmly. Cut into 3 finger sandwiches.
