Ingredients
  

Main Ingredients
  • 1 package Puff Pastry 17.3 oz / 490g, thawed
  • 1 large Egg For egg wash
  • 1 cup Strawberry Preserves 320g
  • 1 tbsp Cornstarch 8g
  • 1 tsp Water 5ml, for slurry
  • 1.5 cups Powdered Sugar 180g, sifted
  • 2 tbsp Heavy Cream 30ml
  • 1 tsp Vanilla Extract 5ml

Equipment

  • 1 Baking Sheet Lined with parchment paper
  • 1 Piping Bag Or zip-top bag for icing
  • 1 Pastry Brush For egg wash

Method
 

Prepare the Filling
  1. Simmer strawberry preserves in a saucepan over medium heat. Add cornstarch slurry (cornstarch and water) and whisk until viscous and dark red. Cool completely.
Assemble the Strudels
  1. Cut puff pastry into rectangles. Place 1.5 tbsp (25g) of filling on half the rectangles, leaving a border. Brush border with egg wash and top with remaining rectangles.
  2. Crimp edges with a fork to create buttery pastry flakes and seal the filling inside.
Bake
  1. Brush tops with egg wash. Bake at 400°F (200°C) for 18-22 minutes until baked golden puff pastry forms with visible flaky layers.
Ice
  1. Whisk powdered sugar, cream, and vanilla. Pipe a heavy, opaque white vanilla icing drizzle in a uniform zigzag pattern over the warm pastries.

Notes

Ensure the filling is completely cool before assembly to prevent melting the pastry.
Sift the powdered sugar to ensure a smooth, professional drizzle.
