In a medium sized saucepan over medium heat, add ginger, water and sugar, and stir well. Allow the water to come to a simmer at most, never to a boil, and simmer for about 15-20 minutes, or until ginger flavor is as strong as you like. Let cool as you make the rest of the lemonade.
1 (3-4 inches) fresh ginger, 2 cups water, 2 cups granulated sugar
Puree the strawberries and raspberries in a blender or in a bowl with an immersion blender, then strain them through a mesh sieve. Set aside.
½ lb strawberries, 6 ounces raspberries
Pour in the lemon juice, strained berries, and half of the simple syrup into a pitcher. Pour the club soda over the lemonade mixture and stir well. Taste, and add more of the simple syrup if more sweetness is needed.
1 cup lemon juice, 1 liter club soda
Cover the pitcher with a lid or tightly with plastic wrap until ready to serve.
Serve over ice and garnish with fresh berries, lemon slices, and mint sprigs.
