last time i made it i made the crust with gluten-free cookies instead of graham crackers. it was really good. i think a nut-based crust would be great too!
What brand of gluten free cookie did you use? I know there is a pretty wide range from yummy to yucky so I want to get a decent one. I have a pretty good gluten free product range available at my store. Crackers I know (I tend to crave salty junk). Cookies not so much so.
