CRUSHS is good on it's own but when you add fun stuff it takes it to the next level.
Mix-ins generally work best with a Creami. Most of the time you'll want to add them after the first spin. Make a little divot in the center of your pint, drop your stuff in along with a splash of milk, then hit the "Mix-In" button. Voila! You've now turned your base into something super special. Don't be afraid to experiment.
