I used a Cuisinart Countertop Ice Cream Maker for my slush. It sits on the counter and the slush is ready in 20 minutes! I think any ice cream churn would work though, but the older style with the ice and salt will certainly take longer. If you do not have an ice cream churn, you can use a sturdy plastic pitcher or other freezer-safe container but the method will change. Refer to the instructions.
