Instructions Checklist
  • Preheat oven to 400 degrees. On a lightly floured surface, roll out pastry 1/8 inch thick. Cut into 8 squares, about 5 inches each; arrange on 2 parchment-lined baking sheets.

  • Stir together rhubarb, strawberries, lavender sugar, cornstarch, and salt. Arrange 1/3 cup mixture in center of each pastry square. Fold edges in; crimp to form rounds. Brush edges with beaten egg white and sprinkle with sanding sugar. Freeze until firm, 20 minutes.

  • Bake, rotating sheet halfway through, until golden brown and fruit is bubbling, 30 to 35 minutes. Transfer to a wire rack to cool. Serve with whipped cream.
