These are great little bites for a hot day, and are easy to do. As long as the watermelon flesh is dark red, the chances are it will be sweet and flavoursome. If there isn’t a cut-open half of watermelon on the stall or the shelf, ask for one to be cut in half. Greengrocers usually sell half watermelons anyway, so if you reject it they shouldn’t mind.
