I'm not really sure where to post this so I'm gonna just leave it here. My boyfriend just came across a recipe for homemade ice cream a couple days ago where you mix milk and vanilla, possibly another ingredient I can't recall at the moment, in one ziploc bag and then fill another with ice and salt, seal and throw it inside the milk bag and shake it up. I'm not sure this would quite work. I'm wondering if anyone has tried making homemade ice cream without an ice cream maker, and if so how?
