This brilliantly colored mocktail will have everyone (including the kids) lining up for a beverage break on hot summer days. Ripe plums, blackberries, and sweet basil are balanced by refreshing lemon soda.
In a bowl, muddle plums, blackberries, basil leaves, and sugar until fruit has broken down. Add lemon soda and stir to combine. Strain into a pitcher, pressing down on solids. Serve over ice with more berries and basil sprigs.
