Need a simple cocktail for a hot day when the thought of lemonade makes your mouth water? Try this one. You start crafting this new signature blender drink by making lemon syrup from scratch from lemon juice, sugar and water. Track down some limoncello-an Italian lemon liqueur-and Smirnoff citrus vodka or your favorite citrus vodka. Now you're just a press of the blender button away from being refreshed.
