Prune Tarts

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the filling

  1. Scald the prunes.

  2. Remove the stones from the prunes.

  3. Break the prunes apart.

  4. Combine the prunes, juice, and sugar in a saucepan.

  5. Simmer the mixture until thickened.

  6. Let the mixture cool.

Assemble and bake

  1. Fill puff pastry with the cooled mixture to make tarts.

  2. Bake in a preheated oven at 400°F (200°C) until golden.

What each ingredient does

Prunes
Provide the main fruit body and deep, sweet flavour of the filling.
Cranberry or currant juice
Adds moisture and a tart fruitiness that softens the filling's sweetness.
Sugar
Adds sweetness and, as it cooks, thickens the juices into a spreadable filling.
Puff pastry
Forms a flaky, layered crust that puffs and browns in the oven.

The step that matters

Let the mixture cool before filling the pastry. A hot filling melts the butter layers in puff pastry before they can set, so the tarts turn greasy and fail to puff evenly.
