Cut puff pastry into 6 equal squares. Place on a parchment-lined baking sheet and refrigerate.
In a medium bowl, mix apples, brown sugar, flour, cinnamon, nutmeg, and cloves. Let sit 10–15 minutes.
Remove pastry squares from refrigerator. Spoon apple mixture onto one diagonal half of each square.
In a small bowl, whisk egg and water to make egg wash.
Brush edges of pastry with egg wash. Fold over to form triangles. Press edges to seal.
Brush tops with egg wash and sprinkle with sugar.
Bake 15–20 minutes or until golden brown.
Notes
Keep Pastry Cold
Cold pastry bakes up flakier. Keep the cut squares in the refrigerator until ready to fill.
Don’t Overfill
Use a small portion of apple filling in each square so the pastry seals well.
Use Parchment Paper
This makes cleanup easier and keeps the turnovers from sticking.
Ingredient Substitutions
Apples
Use Honeycrisp or Fuji apples if you don’t have Granny Smith.
Brown Sugar
White sugar with a teaspoon of molasses can work as a substitute.
How to Store and Reheat
Store cooled turnovers in an airtight container at room temperature for 2 days or in the refrigerator for up to 4 days. To reheat, place in a 350°F oven for 5–7 minutes until warm and crisp again.
