Ice Cream In A Bag

Awhile ago I made some sorbet for Kelly using this technique, but I guess I forgot to write it down. So here it is for my reference, this time producing ice cream (the physics and chemistry are the same with sorbet):

2. Put milk, vanilla, and sugar into the small bag, and seal it.

4. Shake until mixture is ice cream, about 5 minutes.


5. Wipe off top of small bag, then open carefully and enjoy!
