4 oz freshly squeezed grapefruit juice (about 1 large grapefruit)
1.5 oz tequila (about a shot)
1 Tbsp. Agave nectar
Juice of ½ lime
2 jalapeno slices
4 oz. (ish) grapefruit sparkling water (I love LaCroix) or club soda
Instructions
Muddle the grapefruit juice, agave, lime juice, jalapeno, and tequila together in the bottom of a shaker.
Add a few ice cubes and shake.
Pour into a glass with ice, and top with grapefruit sparkling water or club soda. Give it a final mix and serve.
Notes
You may need to adjust the amount of agave, based on the sweetness of the grapefruit. My grapefruit was pretty sweet, so you can always stir in more agave to sweeten if needed.
