In a small saucepan over medium heat, add the raspberries, water, and maple syrup. Cook until thick, about 5 minutes. Use an immersion blender or add the mixture to your blender to puree until smooth. Chill in fridge at least 10 minutes.

Divide mint and 1/2 the lime wedges into drinking glasses. Use a muddler or the end of a wooden spoon to mash them together. Divide raspberry puree, ice cubes and sparkling water between the glasses. Stir to combine and garnish with remaining lime wedges. Sprinkle a pinch of sea salt if desired. Enjoy!
