Rhubarb Sorbet

I honestly havent really shared many frozen fruit desserts on my blog, but this Rhubarb Sorbet was one I had to share. This recipe is inspired by those bright spring stalks that show up when the weather finally starts feeling warm. It’s tart and sweet and it feels so fresh after dinner.

If you love rhubarb in creamy desserts too, try my Rhubarb Cheesecake Bombs. When people think about rhubarb they probably picture pie first because it’s so often baked with sugar. But when it’s simmered gently and blended smooth it turns into the prettiest pink sorbet with a sharp little sparkle.

This recipe is super tasty and quick to make. I recommend this dessert for anyone who wants something cold and fruity without making a heavy baked dessert.

Ingredients

Here’s what I use for this recipe and you can always make substitutions if you prefer.

• fresh red rhubarb stalks: Trimmed and sliced so the sorbet gets bright color and tart flavor.
• granulated cane sugar: Sweetens the rhubarb and keeps the frozen texture scoopable.
• filtered water: Helps the rhubarb soften into a syrupy base.
• fresh lemon juice: Sharpens the fruit flavor and keeps the sorbet from tasting flat.
• fine sea salt: Balances the sweetness and makes the rhubarb taste brighter.
• light corn syrup: Helps prevent hard icy crystals in the freezer.

Tools You’ll Need

• Medium saucepan: Softens the rhubarb into a syrupy base.
• Blender: Turns the cooked rhubarb into a smooth puree.
• Shallow metal pan: Chills the sorbet base faster and more evenly.
• Ice cream maker: Freezes the base while adding a smooth churned texture.
• Freezer-safe container: Firms the sorbet after churning.

Instructions

Step 1: Slice the rhubarb and start the syrup

Set the saucepan over medium-low heat at about 4 on a 10-dial and add sliced fresh red rhubarb stalks, filtered water, granulated cane sugar and fine sea salt. Stir with a slow scraping motion for 2 minutes so the sugar begins to dissolve around the rhubarb. Keep it at 200°F to 205°F for 8 to 10 minutes. You’ll see the rhubarb turn soft and rosy and the liquid will look cloudy pink. Go past 12 minutes and the flavor gets dull and stewed.

Tip: Choose the reddest rhubarb stalks you can find because green stalks taste fine but make a paler sorbet.

Step 2: Cook the rhubarb until jammy

Lower the heat to 190°F and cook for 5 to 7 minutes while pressing the softened fresh red rhubarb stalks against the side of the saucepan in short strokes. Stir from the outer edge toward the center so the thicker pieces break down evenly. The mixture should look loose and jammy with a deep pink color and a few stringy bits. Stop when it coats the spoon lightly. Miss this window and too much water cooks off so the sorbet freezes hard. (My first batch cooked for 15 minutes and turned almost paste-like, so I don’t push it now.)

Tip: If the rhubarb looks dry before it softens, add 2 tablespoons filtered water and keep the heat low.

Step 3: Blend the rhubarb base smooth

Cool the rhubarb base to 120°F for 10 minutes, then add fresh lemon juice and light corn syrup. Blend for 45 to 60 seconds and pulse twice at the end so the texture turns smooth but not foamy. The puree should look glossy and pourable with tiny darker flecks. If you blend while it’s boiling hot, steam can force the lid up and the texture can taste cooked instead of fresh.

Tip: For an extra smooth sorbet, strain the puree once before chilling it.

Step 4: Chill the sorbet base

Pour the puree into a shallow metal pan and chill at 38°F for 2 to 3 hours. Drag a spatula through the center once after 1 hour so the cooler edges mix back into the warmer middle. The base should look thicker and a little darker when cold. Skip this chill and the churn takes too long, which makes large ice crystals form.

Tip: A shallow pan chills faster than a deep bowl and gives the smoothest frozen texture.

Step 5: Churn until softly frozen

Churn the chilled base at 18°F to 22°F for 18 to 22 minutes. Let the frozen mixture fold over itself in slow waves and stop when it mounds softly instead of splashing. You’ll see the color turn lighter and the texture change from glossy liquid to soft pink ribbons. Go too long and the blade smears the sorbet against the sides so it turns dense.

Tip: Freeze the churn bowl for at least 24 hours so the base freezes before it gets icy.

Step 6: Freeze and scoop the sorbet

Pack the soft sorbet into a freezer-safe container and press it into uneven layers. Freeze at 0°F for 3 to 4 hours, then let it sit at room temperature for 5 minutes before scooping. Scoop with firm curved strokes so the surface curls instead of crumbling. The finished sorbet should hold soft ridges and melt at the edges. Serve too soon and it slumps into a puddle.

Tip: Cover the surface with parchment before freezing to keep icy crystals from forming on top.

Pro Tips

• Don’t peel rhubarb unless the stalks are very stringy because the skin gives the sorbet its pretty color.
• Taste the chilled base before churning because frozen desserts taste less sweet once frozen.
• A splash more fresh lemon juice helps if your rhubarb tastes flat or overly sweet.
• Let the sorbet soften for 5 minutes before scooping so it curls instead of cracking.

Storage Instructions

Store Rhubarb Sorbet in a freezer-safe container with parchment pressed directly on the surface. Keep it at 0°F and use it within 2 weeks for the smoothest texture. Let it sit at room temperature for 5 minutes before scooping. For a dessert spread, serve it after Easy Lemon Cream Pie or next to Strawberry Cream Cheese Muffins at brunch.
