Yuzu Watermelon Fizz

1. Cube the watermelon, setting the rinds aside in a separate bowl. Place the watermelon cubes in the fridge to chill.
2. To make the oleo syrup, cover the watermelon rinds with 1 cup sugar (add more if needed to fully coat). Toss well and let sit at room temperature for at least 2 hours, preferably overnight, until the sugar draws out the liquid and dissolves into a fragrant syrup. Strain and discard the rinds, reserving the syrup.
3. Blend the chilled watermelon cubes until smooth, then strain through a fine mesh sieve to remove pulp.
4. In a large pitcher, combine the watermelon juice, yuzu juice, Weber Ranch Vodka, and the watermelon rind syrup. Stir well and chill until ready to serve.
5. To serve, pour the batch cocktail into a cup with ice until ¾ of the way full. Top with seltzer, mint, and enjoy.
