Crisp, refreshing, smooth and silky in texture, this grapefruit sorbet makes a great dessert by itself or cocktail when doused with a shot of gin or vodka.
In a small saucepan, heat 1 cup of the grapefruit juice with the sugar and corn syrup over low heat, stirring just until the sugar is fully dissolved.
Stir the sugar mixture into the remaining grapefruit juice, then stir in the gin or vodka. Chill the mixture thoroughly before proceeding.
Churn the sorbet according to the instructions from your ice cream maker's manufacturer OR pour the mixture into ice cube trays and freeze until solid. If you churn the sorbet, scrape the churned product into a freezer-safe container with a tight fitting lid and freeze for at least 3 hours before scooping.
