1. Whisk together first 3 ingredients and 2/3 cup sugar in a medium-size heavy saucepan. Whisk together half-and-half and next 2 ingredients in a small bowl; gradually add to cornstarch mixture, whisking constantly.

2. Bring to a boil over medium heat, whisking constantly, and cook, whisking constantly, 1 minute. Remove from heat, and transfer to a bowl; cover and chill 4 to 24 hours.

3. Preheat oven to 350°. Pulse wafer cookies and chopped chocolate in a food processor 8 to 10 times or until finely crushed. Stir together cookie crumb mixture, melted butter, and remaining 1/3 cup sugar; firmly press mixture on bottom, up sides, and onto lip of a lightly greased 9-inch pie plate.

4. Bake at 350° for 10 minutes. Transfer to a wire rack, and cool completely (about 30 minutes).

5. Spoon chilled half-and-half mixture into prepared crust. Cut 8 to 10 strawberries in half, and arrange around outer edge of pie (leaving tops on, if desired); hull and slice remaining strawberries, and arrange in center of pie.

6. Cook jelly in a small saucepan over medium heat 2 to 3 minutes or until melted. Remove from heat, and stir in liqueur. Brush jelly mixture gently over strawberries. Chill, uncovered, 30 minutes.
