It is a simple union of buttery puff pastry and sweetened cooked fruit. With the availability of ready-made puff pastry in most grocery stores, turnovers are easy to make. Here is a recipe using the Trader Joe's brand of puff pastry. These puff pastry sheets come flat, making it easy to just pull out and defrost right away.
First, choose apples and pears that are similar in firmness. This ensures that the fruit pieces cook evenly.
2 cups of apples and pears, peeled and chopped into 1/2 inch pieces (about 1 small apple and 1 small pear)
1 tablespoon and 1 ½ teaspoons granulated sugar
1/8 teaspoon ground cinnamon
1/8 teaspoon lemon juice
1 sheet of Trader Joe's Puff Pastry
Place fruit in a bowl with the sugar, cinnamon and lemon juice. Mix well. Pour in a medium sauté pan on medium heat, stirring constantly. Cook until fruit is just softened. Cool completely.
Preheat oven to 350 F.
Take out puff pastry and separate the two sheets while they are still frozen. Cut into 3 inch by 3 inch squares. Work quickly as the puff pastry gets tougher to handle when it is too soft.
Place a scant tablespoon of cooked fruit on each square, at least half an inch from the sides. Beat the egg and add a little water to make an egg wash. Brush each of the sides with egg wash. Fold each square into a triangle. Take a fork and crimp the open edges, sealing the fruit.
Brush the turnovers with egg wash. Take a fork and poke the tops of each turnover to create a vent. This will allow steam to escape. Bake for 20-25 minutes until golden brown. This recipe yields 9 turnovers.
Note: You can use another brand of puff pastry. Just check the defrosting directions.
