Lemon Blueberry Sherbet

Steps

1. 1

   Purée and strain blueberries

   • Place the blueberries in a blender or food processor and blend until completely smooth, about 1 minute.
   • Pour the purée through a fine mesh strainer into a small bowl, pressing gently with the back of a spoon to extract all juice and pulp; discard seeds and any fibrous bits.
   • You should have about 1 cup (240 ml) of strained blueberry purée.

   Ready when: Blueberries completely smooth; liquid passes through strainer easily

   Tip: Straining removes seeds for a silkier texture, though some cooks prefer leaving them in for rustic appeal.

2. 2

   Combine sugar and lemon juice

   • In the chilled metal bowl, whisk together the sugar and fresh lemon juice until the sugar begins to dissolve and the mixture becomes pale, about 2 minutes.
   • Let sit for 5 minutes—the sugar will continue to dissolve and draw moisture from the acid, creating a smooth base.

   Ready when: Sugar granules are no longer visible; mixture is pale yellow and smooth

   Tip: A chilled bowl helps keep the base cold and prevents premature melting when the milk is added.

3. 3

   Add milk and blueberry purée

   • Pour the cold whole milk into the sugar-lemon mixture and whisk to combine.
   • Add the strained blueberry purée and the fine sea salt, whisking gently but thoroughly until the mixture is uniform in color and fully blended, about 1 minute.
   • The base should be a pale lavender-pink and creamy.

   Ready when: All ingredients incorporated; no streaks of blueberry or white milk visible

   Tip: Add salt to brighten the flavor and balance the tartness of the lemon.

4. 4

   Chill the base thoroughly

   • Cover the bowl loosely with plastic wrap and refrigerate for at least 4 hours, or preferably overnight (8–12 hours).
   • This resting period allows the flavors to meld and ensures the base is cold enough for the ice cream machine to work properly.

   Ready when: Base is very cold to the touch and flavors have melded

   Tip: A properly chilled base churns faster and produces a smoother, creamier texture.

5. 5

   Churn the sherbet

   • Remove the pre-frozen ice cream machine bowl from the freezer.
   • Pour the cold blueberry-lemon base into the bowl and attach the dasher according to your machine's instructions.
   • Churn for 25–30 minutes, until the mixture reaches a soft-serve consistency—it should still be slightly soft and have ribbons of sherbet forming as the dasher moves.
   • The surface will look creamy and scoopable but not yet fully frozen solid.

   Ready when: Mixture is pale purple, thick, and holds soft peaks when scooped; dasher requires effort to turn

   Tip: Do not over-churn or the sherbet will become grainy and icy. Stop as soon as it reaches soft-serve stage.

6. 6

   Transfer and freeze

   • Working quickly, transfer the soft sherbet to a freezer-safe storage container, scraping out every bit from the machine with a wooden spoon.
   • Press a sheet of plastic wrap directly onto the surface to prevent ice crystals from forming, then secure the lid.
   • Freeze for at least 4 hours until firm enough to scoop cleanly.

   Ready when: Sherbet is firm enough that a spoon doesn't sink through easily, but a scoop sinks with slight pressure

   Tip: Plastic wrap directly on the surface keeps ice crystals at bay better than just the container lid.
