• Preheat oven to 400°F.

Pastry

• On a parchment lined baking sheet, roll out the puff pastry dough to a large rectangle.
• In a small bowl, whisk together the egg and the water.
• Using a sharp knife, score a 3/4-inch border around the edge of the puff pastry sheet. With a fork, dock the inner rectangle of the pastry sheet.
• Brush the border edges of the pastry with the egg wash. Sprinkle with sparkling sugar if desired.
• Bake for 20 minutes or until golden brown and puffed. Set aside to cool.

Strawberry Topping

• In a large bowl, whip the cream to soft peaks, add the granulated sugar and whip until firm but spreadable. Spread the cream over cooled puff pastry.
• Slice strawberries thinly, about 3-4 slices per berry. Layer berries over the cream topped puff pastry.
• In a separate bowl, mix the strawberry jam and 1 teaspoon of water to thin. Using a pastry brush, brush the jam mixture over the sliced strawberries.
• Keep refrigerated until ready to slice and serve. Garnish with additional whipping cream, confectioners sugar, and mint sprigs. Or... ice cream is especially delicious as well!
