There's no need to spend money on artificial sorbet when you can make watermelon sorbet at home! It takes just 5 minutes to whip up and only 2 ingredients - watermelon and lemon juice. And no, you don't even need an ice cream maker. Let's blend!
Freeze: Freeze watermelon cubes in a single layer on a parchment-lined baking sheet until solid, about 4 hours.
Blend: Transfer frozen watermelon to a heavy-duty blender or food processor. Add lemon juice and blend until smooth, scraping down sides and adding a splash of water as needed to get things moving.
Taste: Taste and optionally blend in honey or simply syrup as needed to suit your taste.
Notes
Store in an airtight container in the freezer for up to 3 months. It may need to thaw slightly before serving to be scoopable!
