A refreshing, jewel-toned sorbet that blends ripe plums with a whisper of warm cardamom and lemon for balance. Naturally dairy-free and vegan, it churns silky-smooth and scoops beautifully for hot days, dinner parties, or an elegant palate cleanser.
Make the syrup: In a small saucepan over medium heat, combine sugar, water, and cardamom, stirring until the sugar fully dissolves. Remove from heat and let cool to room temperature.
Prepare the fruit: Wash, pit, and roughly chop the plums; leave skins on for vibrant color and added flavor.
Blend: Add plums, lemon juice, cooled cardamom syrup, and a pinch of salt to a blender. Blend until completely smooth; taste and adjust sweetness if needed.
Strain (optional): For an ultra-smooth texture, pass the purée through a fine-mesh sieve, pressing with a spatula to remove skins and pulp.
Chill: Transfer the mixture to a covered container and refrigerate until thoroughly cold, at least 2 hours.
Freeze with an ice cream maker: Pour the chilled base into the machine and churn according to manufacturer instructions until thick and creamy.
Freeze without a machine: Pour into a shallow dish and freeze, scraping and stirring with a fork every 30 minutes until evenly frozen and smooth, about 3–4 hours.
Set: Transfer to an airtight container, press parchment or plastic wrap onto the surface, and freeze at least 4 hours.
Serve: Let sit at room temperature 5–10 minutes to soften slightly, then scoop and serve.
