Thaw the puff pastry sheet as instructed on the box. It is very important to thaw the sheets perfectly.
1 box Puff pastry sheet
Add 1 teaspoon of cornstarch to each of the jams and mix well. Skip this step if not using cornstarch.
3 Tablespoon Apple Jam, 3 Tablespoon Strawberry Jam, 2 teaspoon Cornstarch
Preheat the oven to 400 F. Layer a baking sheet with parchment paper or a silicon mat. I like to layer mine just in case there is an accident when baking and the jam seeps out.
Once thawed, open the sheets and separate them. Slightly roll the sheets to make them even and then cut each sheet into 6. This will make 3 strudels. Repeat the same with the other sheet.
1 box Puff pastry sheet
Spread about 1 to 1 ½ tablespoons of jam filling in the center of half the sheets. Leave about ¼ inch space on all sides.
3 Tablespoon Apple Jam, 3 Tablespoon Strawberry Jam
Brush the sides with heavy cream or egg wash.
2 Tablespoon Heavy cream
Now place the other half of the sheets over the layered ones and press it to seal. Use a fork to gently crimp the sheets to seal them well.
Place the prepared toaster strudel onto the prepared baking sheet. Brush the pastries with heavy cream or egg wash.
Bake them in the preheated 400 F oven for about 18 to 20 minutes or until golden brown.
