Directions

Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.

  1. Combine the water and sugar in a saucepan over medium heat, stirring until the sugar fully dissolves and the syrup just comes to a simmer, about 5 minutes.

  2. Remove the pan from the heat, add the basil leaves and lemon zest, and let them steep in the syrup for 10 minutes.

  3. Strain out the basil and zest, pressing gently on the solids to extract the syrup. Stir in the salt, lemon juice and grapefruit juice until combined.

  4. Refrigerate the mixture until completely cold, at least 2 hours.

  5. Churn the cold mixture in an ice cream maker according to the machine's directions until thick and slushy, about 20 to 25 minutes.

  6. Transfer the sorbet to a freezer-safe container and freeze until firm, at least 4 hours, before scooping.
