I know this is very late but I just noticed that I made a huge mistake, I'm sorry for any confusion. I had Indy's and Sugarshack's recipes confused. As previously posted, Indy's does use Crisco and works great, Sugarshack's recipe requires HR shortening. I will try to be more careful in the future.
Indy's recipe is great if you have high-ratio shortening but it absolutely will not come out right with Crisco. I've been there and done that . If you do get hold of some high-ratio shortening and make Indy's recipe it refrigerates without any problem, it's just nice that it's not necessary to keep it cold.
