Had one of these at Olive Garden; delicious on a hot summer day.

4 jiggers limoncello Italian lemon liqueur ¼ cup sugar
4 jiggers lemon schnapps or lemon bar shots 1 lg. lemon, sliced thin
2 jiggers lemon infused vodka (optional)
½ cup lemonade
½ cup club soda

Fill a blender ¾ full of crushed ice, add liqueur, schnapps, lemonade and club soda. Blend. Place sugar in a flat saucer; wet rims of martini 4 glasses and dip each into the sugar to coat the rims. Pour lemonade into the glasses, garnish with slices of lemon.

*If you don’t feel like dragging out the blender, serve over chipped ice. Use only 1 jigger of limoncello and the schnapps.
