Defrost the raspberries. Puree with the cutting stick of the hand mixer. Pass the raspberry puree through a sieve into a metal bowl. Wash the lime hot and rub dry. Then cut in half. Squeeze one half. Stir lime juice, sugar and sparkling wine into the raspberry puree.
Let it freeze in the freezer for 4-5 hours. Stir several times. Cut the rest of the lime half into four slices. Wash the mint. Cut 12 scoops from the sorbet using an ice-ball cutter and fill into four glasses. Serve with lime slices and mint
