Here are a few tips if you decide to do this at home:
- Use freezer bags instead of regular bags. The added thickness helps prevent either bag springing a leak. Alternately, you could place the bag of ice cream mixture inside a can with a lid.
- Wipe off the inner bag, especially around the closure. Eat the ice cream out of the bag. Both of these things help keep salt out of the ice cream.
- Double the recipe provided in the link. More ice cream is better!
Squishing and rolling are the best techniques for making the ice cream.
Some creative mixing!
