When I get a craving for ice cream this is what I make. It's made from frozen bananas. I keep a big bag of bananas with their skin on in the freezer. I take one out about 1/2 an hour before I want to make it. Then I peel it and place it into my mini processor with a few tablespoons of water to make it easier to puree.
Today I flavoured it with some blueberries and strawberries, but I also eat it just on its own.
