- 1½ cups blueberries
- 4 cups white (or red) currants
- A little water
- 1 cup granulated sugar
Put the berries in a medium-sized pot with a few tablespoons water and place over medium-high heat. Bring to a boil and then lower to a simmer, stirring occasionally. Continue simmering until most of the skins have popped, about 10 minutes. Remove from the heat and push the berries through a strainer to extract as much juice as possible. You should have roughly 1½ cups liquid.
Return the berry juice to the pot and add 1 cup sugar. Bring to a boil again and stir until the sugar has dissolved, about 2 minutes. Remove from the stove and let cool. Pour contents into ice cream/sorbet maker and use as directed according to model.
