Just getting into the spirit of the summer. A classic-lemon/lime shakeup. This one is sweetened with Splenda. The fruits are just sliced and tossed into a large tumbler. Add sugar or sweetener to taste and a splash of hot water and mash it up as best you can with a wooden spoon or similar. Top with crushed ice and fill with water or seltzer. Stir some more and taste, add more sweetener if needed. Mmm good. the drink can be topped off with additional water and ice-just give the citrus another good pounding. Similar citrus ades use other fruits, oranges are a perennial favorite. Something to try: Boil the sliced fruits with sugar and water to make a flavored simple syrup.
