Mix with blender in large mixing bowl:
1 can sweetened condensed milk
2 cans Shasta soda, any flavor
It hasta be Shasta, other sodas won't work!
I don't know why, but that's what a friend told me.
Of course, I had to see for myself, Pepsi does NOT work.
Pour into ice cream freezer, add ice, and ice cream salt, and plug it in.
Some ice cream freezers have a light that tells you when it is done. Mine didn't, so just listen to the sound. When it sounds like it is slowing down, check it. I'm sure the newer freezers do everything for you except eat it!
Enjoy!
