That gumbo video had me drooling.
My attempt at home brew tasted great, but the consistency was all wrong - the cream soda base foamed up way too much when I added the butterscotch, and the cream topping just slid to the side, as a result. I'll keep trying, though. (And post a video when I come up with an acceptable result.)
A Universal Orlando cookbook could be brilliant. Thanks for planting that seed. They need to do this!
