This is one of my preferred recipes: it's very simple and easy to make but incredibly good and all your guests will enjoy it so much. Now...as the main ingredient is melon you should choose a really good one as that will make the difference. You might be tempted to add something, well...I did in the beginning, then I just reduced the ingredients at the minimum and that's simply perfect.
If you have the chance to find small melons you can present this starter as you see in the photo, otherwise I serve it in nice cups or glasses. This recipe is highly influenced by the quality of melons that you use.
