1. Prepare Crusts: Preheat oven to 350°. Pulse vanilla wafers in a food processor 8 to 10 times or until finely crushed. Stir together crushed wafers, powdered sugar, and butter in a medium bowl. Press crumb mixture on bottom and up sides of 6 lightly greased 4-inch tart pans with removable bottoms. Place on a baking sheet.
2. Bake at 350° for 10 to 12 minutes or until lightly browned. Transfer to a wire rack. Let cool completely (about 30 minutes).
3. Meanwhile, prepare Filling: Reduce oven temperature to 325°. Beat almond paste and next 3 ingredients at medium speed with an electric mixer until well blended. Pour mixture into crusts.
4. Bake at 325° for 18 to 20 minutes or until set and just beginning to brown around edges. Let cool on a wire rack 30 minutes. Spread 1 1/2 Tbsp. lemon curd onto each tart. Cover and chill 1 to 24 hours. Remove tarts from pans, and top with raspberries just before serving. Garnish, if desired.
