Cut several large bunches of lilac blossoms. Remove the florets, making sure to remove any bitter green stems.
Rise the florets in a fine mesh strainer under cold water.
In a small saucepan, combine water and sugar and bring to a boil over medium heat. Stir until the sugar is completely dissolved.
Add the lilac blossoms to the saucepan and stir gently. Cover and simmer for about 5 minutes.
Remove the saucepan from the heat, keep it covered, and allow the blossoms to steep from 3-8 hours, depending on how potent you'd like the lilac flavor to be.
Pour the mixture into a fine mesh strainer over a bowl. Allow the syrup to drain, shaking the strainer occasionally. Store the syrup in a glass container with a tight lid in the refrigerator.
Lilac Lemon Drop Martini
Rim a martini glass with a lemon wedge and dip in the infused sugar.
Pour the vodka, lemon juice, and lilac simple syrup in a martini shaker with ice. Shake well and strain into the rimmed martini glass.
Add a lemon wedge and extra lilac blossoms as a garnish as desired.
