If you don't already have one, you must put it immediately on your Christmas list. I bought ours a few years ago for DH (but actually the whole family too). This is certainly not the way you want to make ice cream everytime you have it, but it is enjoyable once in a while, and it really allows you to have fun and make some really unique flavors. You can find all sorts of recipes online for the ball:
You only need rock salt, a bit of ice, and a whole lot of shaken to make the ingredients turn into yummy, yummy ice cream.
We made coffee ice cream this particular day - my favorite. Of course between the coffee ice cream and the large hazelnut coffee from Dunkin Donuts (both after 8pm), I did not fall asleep very well that night.
