This is such a refreshing slushie for a hot summer day. Simply take one honeydew melon and slice the flesh into cubes. Put them in a plastic container and put in the freezer overnight or until frozen. Then into your smoothie maker add as many of the frozen melon cubes as you can fit up to the max fill line. Add about a tablespoon of honey, as well as the juice and zest of half a large lemon. You will need to add some water in order to get it to blend easily. Start by filling the smoothie maker cup 1/4 of the way with water. Then blend everything together. If you find it is not blending easily then add a little more water and try again as required. Once it is blended there will be more room in the cup and so you can add more cubes of the frozen melon. Blend again and repeat until you have used about half of the melon cubes. To serve I found it easiest to spoon the slushie into glasses.
