This was something that I didn't know that I needed. It was a little more work than I was expecting, but it's completely worth it. This makes the perfect portion of the best ice cream I've ever tasted. I love that it's a few simple ingredients. This takes a little work and preparation. You need to freeze the empty mug for at least 24 hours. After you heat the ingredients, you have to allow them to cool, before putting them in the ice cream maker. I also put the ice cream back into the freezer, for a few hours, so it could be firmer. This isn't an instant ice cream option, but if you can be patient, you will be in for quite a treat. I loved every creamy bite.
