Reserve 1/4 cup Fresh Mixed Berries (1/4 cup) for later.
Place one cup Fresh Mixed Berries (1 cup) in a large glass bowl or glass with the Rock Salt (1/4 teaspoon) and Pure Maple Syrup (1/2 cup). Muddle well, mashing the berries on the sides of the bowl to release as much juice as possible.
Strain into a pitcher by pushing through as much juice as you can collect. Add some water and strain again.
Add Water (3 cup), Lime (to taste) juice and maple syrup to sweeten. Taste and adjust sweetness adjusting the lime juice and or maple syrup as required. Add a few whole fresh berries and Fresh Mint Leaves (to taste).
Chill well before serving, else pour over ice!
