In a blender, add cherries, lime juice, lime zest, and maple syrup. Blend until completely smooth.
Chill this until nice and cold OR if you're pressed for time, grab some ice and fill two glasses halfway.
Distribute cherry-lime juice between two glasses. You can strain it for an even smoother finish if you'd like.
Top of with seltzer. Serve and savor the sweet and tart flavors of summer!
