　　In Epi's 3-Ingredient Recipes series, we show you how to make great food with just three ingredients (plus staples like oil, salt, and pepper).

　　Save your fresh berries for eating out of hand: Frozen blueberries have a more intense color and concentrated flavor then fresh ones, so your granita will be deep violet and sweet.

　　

Ingredients

Serves 8–10

　　1 cup sugar

　　1 (10-ounce) bag frozen blueberries

　　1 (750-ml) bottle sparkling wine

　　

Step 1

Bring sugar, 1 cup blueberries, and 1 cup water to a boil in a small saucepan; cook, stirring, until sugar dissolves, about 5 minutes. Transfer blueberry syrup to a medium bowl set inside an ice bath and let cool.

　　

Step 2

Purée syrup and remaining blueberries in a food processor until smooth. Strain mixture through a fine-mesh sieve into a 13x9" (or other 3-qt.) freezer-safe baking dish, pressing on solids to extract as much juice as possible; discard solids.

　　

Step 3

Pour sparkling wine into baking dish and stir to combine. Freeze mixture until just beginning to crystallize, about 2 hours. Scrape with a fork, then continue to freeze, scraping every hour, until texture is similar to shaved ice, 3–4 hours more. Cover with plastic wrap and keep frozen until ready to serve.

　　

Do Ahead

Step 4

Granita can be made 5 days ahead; keep frozen.
