Nutrition (per serving)
Method
Combine the water and caster sugar in a medium saucepan. Place over medium heat and bring to 100 Celsius/212 Fahrenheit to create a simple syrup.
Add the fresh blackberries to the bubbling syrup. Reduce the heat to low and simmer until the berries soften and release their juices into the liquid.
Remove the saucepan from the heat. Carefully transfer the hot berry mixture to a blender and process until completely smooth.
Pour the blended mixture through a fine mesh sieve into a mixing bowl. Press firmly on the solids with a spoon or spatula to extract as much liquid as possible, then discard the seeds.
Stir the elderflower cordial and fresh lemon juice into the smooth blackberry base. Cover the bowl and refrigerate until thoroughly chilled, ideally reaching 4 Celsius/39 Fahrenheit.
Pour the chilled base into your ice cream maker and churn according to the manufacturer guidelines until it resembles thick slush.
Transfer the softly churned sorbet into an airtight container. Freeze at -18 Celsius/0 Fahrenheit until fully firm and scoopable.
Chef's Notes
- Elderflower cordial can vary widely in sweetness and acidity. Always taste your base before freezing; it should taste slightly sweeter and tarter than you want the final sorbet to be, as freezing mutes flavors.
- Do not skip straining the blackberry seeds. Their woody, gritty texture will severely detract from the velvety mouthfeel of a premium sorbet.
- For an even smoother texture that resists icy crystallization over time, you can replace 30g of the caster sugar with an equal weight of liquid glucose or light corn syrup.
- If you do not own an ice cream maker, you can pour the chilled base into a wide, shallow dish and place it in the freezer. Scrape it vigorously with a fork every 30 minutes for about 3 hours to create a fluffy granita.
Storage
Freezer: 1 month — Store in a shallow airtight container with a piece of parchment paper pressed directly onto the surface to prevent ice crystals.
