In a small saucepan combine sugar, lavender and water.

Bring to a boil, at which point sugar should be completely dissolved, creating a syrup.

Remove from heat and allow to cool, steeping lavender for approximately 20 minutes.

Pour syrup through a strainer, straining out the lavender.

Place simple syrup into the refrigerator until cold.

Rim a highball glass with sugar.

Fill the glass with ice and a slice of lemon.

In a shaker filled with ice, combine 1 Tablespoon of the simple syrup, lemon juice, tonic and vodka and shake until cold.

Strain into ice-filled glass.

Enjoy!
