Smitten uses their own magical liquid nitrogen ice cream machine, called "Brrr" (masters of comedy, no?). It allows them to make ultra smooth ice cream to order in seconds, which is a marvel. I tend to get sundaes, and I wasn't blown away by the "Dough My Goodness" or "Berry Crisp" sundaes on offer that day, but they certainly were as smooth as promised. I'll go back to see if their more inventive flavors can earn that last star.
