A few weeks ago, I had some watermelon I couldn’t finish. So I decided to blend the watermelon, drained it through a sieve, and froze it for future use. I knew I wanted to make a Watermelon Mojito and having the frozen watermelon puree would make the process much easier.

So when I was contacted by Polar Seltzer to try some of their summer seltzers, I knew the time had arrived. Even better, one of the flavors sent my way was Mint Mojito!

So I broke out the Watermelon puree and let it thaw in the refrigerator. You can also blend fresh watermelon right before making the mojitos.

Ingredients (Makes 1, multiply as needed):
- 4-5 mint leaves, plus more for garnish
- the juice of 1 lime
- 1 tablespoon agave (I used Agave in the Raw)
- 2 oz white rum
- 3 oz watermelon puree
- Polar Mint Mojito Seltzer
If you are pureeing the watermelon, cut the meat of the watermelon from the rind. Roughly chop and throw into a blender. Blend until pureed. You might need to add a bit of water to the blender to get everything going. Pour the puree through a fine mesh sieve using a spoon to push it through.

To make the mojitos, add the mint leaves and lime juice to a mixing glass. To make juicing the lime easier, I used the IMUSA lime squeezer (affiliate link). Muddle the mint and lime juice together (if you don’t have a muddler, you can use a spoon).

The seltzer is so fantastic in this drink. The carbonation adds freshness to the already refreshing watermelon and the mint flavor helps bring out the fresh mint as well. I also love the color!
