Black and Blue Berries in Ginger Syrup

Ingredients
2 cups water
2 1/2 cups blackberries, divided
1/3 cup turbinado or granulated sugar
2 (1-inch) pieces peeled fresh ginger, thinly sliced
2 (3-inch) strips lime zest
2 tablespoons fresh lime juice
2 cups blueberries
2 cups lemon sorbet (optional)
Preparation

1. Bring 2 cups water, 1/2 cup blackberries, sugar, ginger, and lime zest to a boil over medium-high heat in a saucepan, stirring just until sugar is dissolved. Boil for 5 minutes. Remove saucepan from heat, and let stand, covered, for 5 minutes. Pour mixture through a fine strainer set over a bowl; don't press on solids. Reserve the syrup, discarding the blackberries. Then stir in the lime juice.

2. Add the remaining 2 cups blackberries and blueberries to the syrup. Serve over 1/2 cup lemon sorbet, if desired.
