This option is a bit more work, but worth it. First, you make lavender syrup, using ½ cup of water, ½ cup of sugar, and 1 tablespoon of dried lavender. Bring it to a boil, and then turn off the heat and let it cool. Strain the solids out before using it. Combine ¼ teaspoon of Grenadine, ¼ cup of lemon juice, and 1 ½ tablespoons of the syrup you made in a shaker with ice. Shake it up, strain it into a glass, and fill the glass with club soda. For a pretty touch, garnish with a sprig of lavender.
