Ingredients

Directions

The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Preheat the oven to 400°F (200°C).

Make the filling

  1. In a bowl, mix the mashed potatoes with currants, sugar, candied peel, beaten eggs, and butter until well combined.

  2. Flavor the mixture with a few drops of lemon or vanilla essence.

Bake

  1. Line patty tins with short crust pastry.

  2. Drop a teaspoonful of the mixture into each lined tin.

  3. Bake for about 15 minutes until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Mashed potatoes
Provide the bulk and a soft, moist body to the filling.
Eggs
Bind the mixture and help it set as it bakes.
Butter
Adds richness and moisture to the filling.
Castor sugar
Adds sweetness and helps the top brown during baking.
Currants
Add chewy pockets of fruit sweetness throughout the filling.

The step that matters

Bake until golden brown. The filling is soft and set mainly by the eggs, so underbaking leaves it wet in the middle, while overbaking dries it out and darkens the pastry too much. Watch the color closely near the 15-minute mark.

Swap the currant

How well each one fits the dish's main ingredients (potato, sugar, butter, egg, lemon):
