Plum and Blackberry Sorbet Recipe — Refreshing Summer Dessert

Homemade sorbet has been a favorite all summer. With simple ingredients and no dairy, it’s an easy, affordable frozen dessert. This plum blackberry sorbet combines the best of both fruits: sweet, tangy, and silky smooth, made with only a few ingredients.

Homemade Sorbet Ingredients

Sorbet is refreshingly straightforward: fruit, water, and sugar. Depending on the fruit you use and whether you puree or juice it, the exact proportions can vary, but each component has an important role.

Using fruit puree instead of juice gives the sorbet more body and natural pectin, which helps create a creamier texture. Plums are naturally high in pectin, making them a perfect partner for blackberries, which have less. I usually use fresh or thawed frozen fruit that I puree and strain, adding water only to reach the right consistency for churning.

Fruit Puree or Juice

The fruit puree is the flavor base and also affects texture. Pureeing whole fruit results in a thicker base with natural pectin, helping produce a smooth, luscious sorbet.

Sugar

Sugar is essential for texture and freezing. It limits large ice crystals and encourages small ones, keeping the sorbet smooth. When you start with a thick fruit puree, you can use less sugar and let the fruit flavor shine.

Optional ingredient — Lemon

A splash of lemon brightens the fruit flavors and balances sweetness. It’s optional, but I find a little lemon juice enhances the overall taste.

Making Homemade Sorbet

Sorbet requires some waiting time, but the hands-on work is minimal. If you want a quick blackberry dessert, other recipes may be faster, but this one rewards patience with excellent texture and flavor.

Step 1 – Make the Sorbet Base

Before starting, freeze your ice cream maker bowl according to the manufacturer’s instructions — overnight if possible. The sorbet base keeps in the fridge for up to 24 hours if you need to wait.

Pit and slice plums, then combine them with blackberries and water in a blender or food processor. Puree until very smooth, then pour the mixture through a fine mesh sieve set over a saucepan to remove seeds and thick pulp. A rubber spatula helps speed straining by moving the puree across the mesh; scrape the underside of the sieve to recover any remaining puree.

  • a strainer with blackberry pulp and seeds in it

Once strained, you’ll be left with mostly seed pulp in the sieve. Discard that, then add the strained puree back to the saucepan with sugar and lemon juice. Warm gently over medium-low heat, stirring until the sugar dissolves. Cool the mixture and chill in the fridge for at least one hour, up to 24 hours, before churning.

Step 2 – Churn

Assemble your ice cream maker and turn it on so the bowl is spinning as you add the chilled sorbet base; this helps prevent splashing and reduces wasted mixture on the bowl sides. Churn according to your machine’s instructions — typically 10 to 20 minutes — until the sorbet is thick and smooth.

After churning you can enjoy the sorbet immediately for a soft-serve texture or transfer it to freezer-safe containers and freeze at least one hour for a firmer scoopable texture.

Questions

Can I leave the lemon out?

Yes. Lemon brightens and balances the sweetness, but the sorbet will still be tasty without it if you prefer a more intensely sweet result.

Do I need an ice cream churn?

It’s not strictly necessary. You can freeze the base in a shallow container and stir every 20 minutes to break up ice crystals until frozen, though churned sorbet is usually creamier. An inexpensive electric maker saves time and yields more consistent results.

How do I use frozen fruit?

Thaw frozen fruit before blending so your blender can extract maximum juice and flavor. Blending frozen fruit can require extra water and dilute the flavor.

How long will it last in the freezer?

Stored in an airtight container, sorbet keeps well for about two months without noticeable loss of quality; after that the texture may change.

Enjoy!

This recipe is hands-on for only a short time and rewards you with a freezer full of fresh, dairy-free sorbet. Make it while plums and blackberries are in season, or use frozen fruit when needed. Happy eating!

Notes
