Step 1In a large bowl, stir together the cookie crumbs, ground pecans and powdered sugar.
Step 2In a microwaveable bowl, microwave the chocolate until it's melted (I usually do it for 30 seconds, then in 10-second intervals, stirring between each interval, and stop before they're totally melted because they'll melt as you stir). Stir in bourbon and corn syrup to combine (the chocolate will seize a bit and the bourbon won't incorporate well. Just do the best you can).
Step 3Add the chocolate mixture to the crumbs mixture, and stir until thoroughly combined. Cover and chill at least 30 minutes.
Step 4Pour some granulated sugar into a dish. Form the chocolate mixture into small balls the size of grapes, and roll each ball in the sugar.
