I have some grain alcohol and lemons and I was thinking about giving it a shot. Had anybody ever tried this before, or consumed anybody else's homemade limoncello?

I was going to follow this recipe but use grain alcohol instead of vodka: http://www.foodnetwork.com/recipes/giada-de-laurentiis/limoncello-recipe/index.html

I still desire a 30-32% ABV so would adjust ingredient proportions of course.
