1 1/2 pounds rinsed blackberries
2 cups brewed black Darjeeling or Assam tea
1 1/4 cups sugar

In a blender, whirl blackberries until puréed. Pour through a fine strainer into a bowl, pressing pulp with a spatula to extract as much juice as possible; you should have 2 cups purée. Discard solids. Whisk tea and sugar into purée. Cover and chill until cold, at least 3 hours or up to 1 day. Freeze in an ice cream maker (at least 1 1/2-qt. capacity) according to manufacturer’s instructions until machine stops or dasher is hard to turn. Transfer sorbet to an airtight container and freeze until firm, about 3 hours.
