Fill each glass with 5 mint leaves, ¼ cup fresh berries, 1 ounce lime juice, and ½ ounce agave nectar. Briefly muddle together with a cocktail muddler or back of a wooden spoon until the berries are smashed and you can smell the mint. Next, pour 1½ ounces white rum into each glass, fill both at least half-way with ice, and top with seltzer or club soda. Add a straw to both cocktails, stir once more, and garnish with sliced lime and additional mint leaves.

Tips:

• Suggested glass size is 10 or 12 ounces for a more traditional cocktail; grab a larger glass and more seltzer or club seltzer for an effervescent highball.

• Feel free to switch up the berries with the juiciest you can find or forage—blueberries and currants are equally lovely, as are the practically tropical vibes of watermelon berries mingled with the lime, mint, and perhaps a bonus of some fresh basil.

• Crushed ice is nice if you have a blender or mallet handy, but-regular cubes work.

• Skip the booze: Omit the alcohol and increase the agave and lime juice to taste for a refreshing mocktail.

• Serving suggestions: Enjoy these cocktails with a bowl of warm stovetop popcorn, drizzled with a little extra virgin olive oil and tossed with this writer’s go-to seasoning blend of nutritional yeast, smoked salt, hot paprika, and garlic powder.
