Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the filling
Beat lemon peel and sugar in a marble mortar.
Add mashed potatoes and melted butter, mixing well.
Stir in cleaned currants.
Bake
Fill pastry crust in patty pans a little more than half full.
Sprinkle with double-refined sugar.
Bake in a 400°F (200°C) oven for about 30 minutes.
