Heat the blackberries, 1 cup of the coconut water, and monkfruit sweetener in a small saucepan over medium heat. Gently mash the blackberries with a wooden spoon or fork to release some of the juices. Stir to combine the ingredients.
While the liquid mixture is heating, cut your lemons in half and squeeze out as much juice as possible into a small bowl. Strain the seeds out with a mesh strainer and discard.
Pour the heated mixture into a large mug or measuring glass while straining out the blackberries with a mesh strainer. Discard the blackberries. Allow the mixture to cool for at least 5 to 10 minutes.
Once the liquid mixture has cooled, combine it with the lemon juice, 1 additional cup of coconut water, and salt.
Chill and pour over ice. Garnish with additional blackberries and lemon if desired. Enjoy!
Notes
I use a mesh strainer like this one to strain the lemon seeds out, and to strain the blackberries out.When combining all the liquid ingredients in step #4, I like to add everything into a cocktail shaker with ice to really get it nice and cool. Then I strain it into a new glass with fresh ice.
