The National Unity Pie: Southern Pecans and Bourbon, Northern Maple Syrup
I like a butter crust (as opposed to lard or shortening) as in the recipe above with a modification, I would go with a vodka crust (substitute cold vodka for the water) for that extra flaky crispness. Here is an alternative tested vodka crust recipe.
The science is settled: Vodka is approximately half water and half alcohol. The alcohol burns off faster and it leads to a better crust through chemistry. If you want to experiment you could try bourbon which would import all the bourbon barrel flavors to the crust. I have not ever done that, but it could be good--or not so good. You might want to try a test sample first.
