Marcia Smart says a dry January "clears the cobwebs."
You can always add a splash of tequila (an ounce or two is perfect) to this cocktail, but it’s refreshing and alcohol-free on its own.
¼ cup fresh grapefruit juice
1 Tablespoon fresh lime juice
1 teaspoon agave (omit for Whole30)
¼ cup club soda or sparkling water
Optional garnish: A small grapefruit or lime wedge or fresh mint or rosemary
Combine the grapefruit juice, lime juice and agave in a glass; stir until the agave is dissolved. Stir in sparkling water and add ice
Place the grapefruit wedge, if using, on the rim of the glass and add a sprig of fresh mint or rosemary.
