Oh, sure, you can use your ice cream maker to churn endless varieties of ice creams and sherbets, but why not use it to make frozen drinks, as well? It can be a bartender's best friend!
Just add the cocktail ingredients to the bucket (you won't need to add any ice since the ice cream maker will do the freezing) and let churn for about an hour before the party. Once the mixture is slushy, place the bucket on the table for guests to scoop their own. Easy peasy!
