Pine Pastry

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Preheat the oven to 350°F (175°C).
In a bowl, whisk together the eggs and sugar until well combined.
Gradually mix in the potato flour and melted butter.
Stir in the lemon juice and grated lemon rind.
Line pattypans with thin puff pastry and fill them two-thirds full with the mixture.
Bake for about 20 minutes until set and lightly golden.
