1. Simmer the sugar and water in a small saucepan over medium-high heat. Stir frequently to dissolve the sugar.
2. As soon as the sugar dissolves, remove from heat and chill in the refrigerator. It will store for several weeks.

For Blackberry-Cucumber-Vanilla Vodka Spritzer

1. Cut the cucumber into chunks and add to the blender with a splash of water. Blend until smooth. Place a bowl underneath a fine-mesh sieve and pour the cucumber puree into the sieve. Discard the solids collected in the sieve and use 1/4 cup of cucumber juice for cocktail.
2. Add the cucumber juice along with blackberries and mint to a cocktail shaker and muddle until the berries break down.
3. Add the vanilla vodka, lime juice, simple syrup and a handful ice. Shake for about 15-30 seconds until the shaker turns frosty. Replace the top of the shaker with a strainer and pour into highball glasses with ice. Top with desired amount of La Croix Muré Pepino or sparkling beverage of your choice. Garnish with additional lime, mint and a blackberry if you'd like. Enjoy!
