Cook's Illustrated has developed a recipe for pie dough that substitutes vodka for some of the water, making dough mixable but developing less gluten (tough pastry). It works! Has anyone tried using rum or whiskey in place of vodka, in hopes of getting a flavored crust, for perhaps a pecan or banana cream pie? If so did it work out for you?

Yes. We use apple jack in apple pie crust, which is a hard liquor with a sweet apple flavor. (As I recall, we took this idea from Alton Brown in an Apple Pie episode.) The apple jack provides the same benefit for flaky crust, and more apple flavor.

1We haven't done a strict side-by-side apple pie test of vodka crust vs. apple jack crust, but the apple jack inclusion is the recipe our household swears by.– KatieKAug 9, 2013 at 18:29

In the (extensive) comments after his newest pie crust article, as far as using other spirits, Kenji Alt says "definitely worth a try, though I've never actually been able to taste any flavor off of the booze or liquid I use in a pie crust, it's such a small amount. If you really strain you can taste it, but it's not obvious..." sweets.seriouseats.com/2011/07/…– SAJ14SAJAug 13, 2013 at 12:58
Judging by the recipe posted on Serious Eats, there are about 2 tablespoons of vodka per crust. Substituting two tablespoons of rum or other liquor may be enough to lend a minimum of fragrance, but I would not expect a strong flavor. I am not sure it would be perceptible in the over all flavor balance of the complete pie with its filling. You would need to use an extract (which is much stronger) to get a robust result.
On the other hand, if you are substituting for convenience because you don't have vodka conveniently available, as long as the proof or alcohol percentage is compatible to vodka, the chemistry will be the same.
