Make your own lemon cups. Some Spanish restaurants serve lemon sorbet in lemons which are actually very easy to prepare and make a nice alternative to a dish or glass. To make your own lemon dishes, cut off the top third of each lemon (this will be the lid once the lemon is full of sorbet) and then hollow the lemons and lids out using a grapefruit knife to avoid cutting through the skin. Then cut a small slice out of the bottom of each lemon (without cutting through to the flesh), so that it stands firmly. Put the lemons and their lids in the freezer for a couple of hours minimum so that they harden. Take them out and fill each lemon with sorbet. Put the lids on, and put them into the freezer again until you are ready to serve them (you can keep them in the freezer for as long as a week)
