Fill an ice cube tray with orange juice and let freeze Peel and slice bananas (I've found 1/8-1/4 inch slices easiest to work with) Put bananas into a container and sprinkle with sugar, close the container and shake to coat slices then place in freezer for a few hours or overnight Place all of the frozen bananas in a blender Pour in the orange juice Add the orange juice cubes Blend until smooth I will add a little half-and-half for some fat or maybe some frozen yogurt, and it comes out velvety smooth and so quenching on a hot South Florida afternoon.
