How to Make It
Preheat oven to 350°.
To prepare crust, place first 6 ingredients in a medium bowl. Beat with a mixer at medium speed 1 minute or until well combined. Weigh or lightly spoon flour into a dry measuring cup; level with a knife. Add flour and nuts to butter mixture; beat until just combined. Divide dough evenly among 24 miniature muffin cups coated with baking spray. Press dough into bottom and up sides of muffin cups. Bake at 350° for 15 minutes or until golden brown. Cool in pan on a wire rack for 5 minutes. Carefully remove from pan; cool completely on wire rack.
To prepare filling, place apple and juice in a bowl; toss to coat. Add 2 tablespoons sugar and the next 4 ingredients (through ginger); toss well.
Melt 1 tablespoon butter in a medium saucepan over medium heat. Add apple mixture; cover and cook 5 minutes or until apple is tender, stirring occasionally. Combine cornstarch and 1 tablespoon water in a small bowl. Stir cornstarch mixture into apple mixture; cook 1 minute or until mixture thickens, stirring constantly. Place apple mixture in a bowl; cool to room temperature. Spoon about 2 teaspoons apple mixture into each tart shell. Top each tart with 1/2 teaspoon crème fraîche.
