Blend in walnuts , sugar, yolk and peel using on/off turns. Combine orange juice and water. With machine running add liquid through feed tube and mix until dough starts to come together; DO NOT FORM BALL. Gather dough into a ball, flatten into a disc. Wrap in waxed paper and refrigerate for one hour or up to 2 days.

Step 5: Set pie shell on baking sheet and place in oven. Pour filling into shell. Bake 15 minutes. Reduce oven temperature to 325 degrees F and continue baking until center is firm and puffed (40-50 minutes). Turn oven off and let pie cool in oven with door ajar.
Step 6: To make the whipped cream: Beat cream until soft peaks form. Add bourbon, sugar and vanilla and continue beating until cream mounds gently. Spoon into pastry bag fitted with a star tip. Pipe decoratively onto center of pie.
