2 slices jalapeño with seeds, plus more for garnish
3 lime wedges
2 tablespoons apricot-mango nectar
2 ounces seltzer water
1 cup sugar
Equipment
whisk
pot
Directions
Combine the sugar and 1 cup water in a small sauce pot over medium heat. Bring to a simmer and cook, whisking occasionally, until the sugar dissolves, about 5 minutes.
Remove from the heat and cool to room temperature. Refrigerate in an airtight container for up to 2 weeks.
Combine the mint, lime wedges, jalapeno and 3/4 ounce of the simple syrup (1 1/2 tablespoons) in a cocktail shaker and muddle. Fill the shaker with the ice, pour in the rum and mango nectar and shake briefly.
Pour directly into a highball glass. Top off with the sparkling water and stir briefly.
