Blueberry Granita

Thoroughly wash the blueberries and let them drain well.

Place the blueberries with lemon juice, powdered sugar and blueberry juice into a tall container.

Puree everything finely until no large pieces remain.

Season the mixture and, if necessary, adjust with a little lemon juice or powdered sugar.

Either freeze in an ice cream maker until granita forms, or pour into a shallow metal bowl and place in the freezer for about 3 hours.

When freezing in the freezer, vigorously stir with a fork every 30–45 minutes and scrape the frozen edges, until a crystalline texture forms.

Serve the granita immediately or just before serving scrape it with a fork once more.
