How it works is to put the container in the freezer for a day before you want to make ice cream.
One thing to note is...
When you pull it out to make your ice cream be sure and put the blade and lid on before you put your ice cream mix in. (Yes I tried putting the mix in first but it did not work so well! lol :) But after having to start over I realized that was the reason for the hole in the top of the lid that I hand wondered why was there! haha ) Once you have it together turn it on as you are adding your mix and it will start turning the blade to make the ice cream
the link below is for one on amazon that kind of look like the one I have. But I only paid $10 for mine.
The lemon zest really gives it a fresh flavor!
