- Always use egg wash for a golden baked puff pastry.
If you don't want to include eggs you may use milk as an alternative.
Brush over milk or melted butter over the puff pastry.
Let the prepared blueberry filling cool down a bit before adding to the puff pastry. This ensures even cooking.
You may also prepare the blueberry filling and stuff in the puff pastry and freeze. This is an easy prep work and make the turnovers as and when required.
Always handle the puff pastry chilled. You may thaw them as needed and put them in the fridge untill you start baking.
Don't over fill the puff pastry with the turnovers. This results in smudging of the filling.
