Cool down your Valentine's Day with a refreshing raspberry sorbet. With the help of a food processor, you can easily make this fruity and tangy dessert. Blend fresh or frozen raspberries, sugar, lemon juice, and a splash of water in the food processor until smooth. Pour the mixture into a shallow dish and freeze for a few hours, stirring occasionally to prevent ice crystals from forming. Serve the sorbet in pretty bowls or garnish with fresh mint leaves for an extra touch of elegance.
