Preheat the oven to 400 degrees. Peel and cut the apples. Sauté briefly in one tablespoon of butter over medium heat. Stir in the Spiced Peach Butter and bring to a simmer. Turn off the heat and let cool.
Roll out the puff pastry on a well-floured surface. Cut into six rounds, each about 4 to 5 inches in diameter. Divide the apple mixture between the puff pastry rounds. Gently turn up the edges, squeezing together as necessary to hold the filling in place and form a tart. Place on a cookie pan and bake until the puff pastry is golden brown, about 15 – 20 minutes. Serve warm or at room temperature. Makes six tarts.
