This drink tastes best with Rose Syrup, a thick pink syrup found in Indian food stores. If you don't have that, substitute equal parts rosewater and grenadine.

If your lemonade comes from a powder mix (the way I make it), prepare half a glass of strong lemonade. Add a half shot of the Rose Syrup or rosewater/grenadine mix, a shot of vodka and a handful of ice. Mix well and then fill with Tonic water (seltzer). Garnish with a slice of lemon and enjoy on a hot summer day.
