The next step is crucial! DO NOT MIX INGREDIENTS INTO BIG BAG!!! This will mess it all up. All your simply doing is shaking the bag GENTLY, not allowing the mixture in small bag to spill out!
Once you correctly have shaken the bag for a good 10 minutes, take the small bag out. Throw large bag away.
Cut the bottom corner of the small bag, clean the bag, and there you go. Ice cream! Many more guides on the way :). Ohh and I'll update it every once in a while!
