To Jazz up your summertime drinks try this trick:

Place an edible flower, raspberry or mint leaf, etc into each square of your ice cube tray. Fill the tray with cooled Boiled water (boiled water no longer has air bubbles so your cubes will be crystal clear). In Spring or during winter months add bits of grated orange peel or lemon zest, brandied cherries, etc.

Delicious and Pretty.
