Step 1

Preheat your oven to 400°F.

Step 2

Roll the defrosted puff pastry out onto a baking sheet to smooth the creases. Don’t worry about the edges being perfect.

Step 3

Place the berries in a colander and rinse well, then transfer to a medium size bowl.

Step 4

Add the brown sugar, cinnamon, and corn starch and mix gently to combine.

Step 5

Spoon the berry mixture onto the puff pastry, leaving about a 1 1/2-inch bordered of pastry uncovered.

Step 6

Fold the edges of the puff pastry over the berries some, tucking the corners under.

Step 7

Lightly beat the egg and brush onto the puff pastry.

Step 8

Bake for 15-20 minutes, or until golden brown.

Step 9

Serve as is, with a dusting of powdered sugar, or with a scoop of ice cream.
