🥗 Ingredients

The Fruit Base

  • 24 ounces Fresh or Frozen Raspberries (thawed if using frozen)
  • 2 tablespoons Fresh Lemon Juice (strained to remove pulp)
  • 1 teaspoon Lemon Zest (finely grated)
  • 1 pinch Sea Salt (to enhance the berry flavor)

The Keto Syrup

  • 3/4 cup Allulose or Erythritol Blend (powdered version preferred for smoothness)
  • 1/2 cup Water (filtered)
  • 1 tablespoon Vegetable Glycerin (optional; prevents the sorbet from freezing rock-hard)
  • 1 tablespoon Vodka (optional; keeps the texture soft and scoopable)
  • 1/2 teaspoon Pure Vanilla Extract (high quality)

For Garnish

  • 6 sprigs Fresh Mint Leaves (for a pop of green)
  • 12 pieces Whole Raspberries (reserved for topping)

👨‍🍳 Instructions

  1. 1

    Place the canister of your ice cream maker in the freezer at least 24 hours before you plan to churn to ensure it is completely frozen.

  2. 2

    In a small saucepan over medium heat, combine the water and the powdered keto sweetener. Stir constantly until the sweetener is fully dissolved and the liquid is clear.

  3. 3

    Remove the syrup from the heat and stir in the vegetable glycerin and vodka (if using). These ingredients are the secret to a soft, professional texture in sugar-free frozen desserts.

  4. 4

    In a high-powered blender, combine the raspberries, lemon juice, lemon zest, vanilla extract, and sea salt. Pulse until the mixture is a completely smooth purée.

  5. 5

    Pour the raspberry purée through a fine-mesh sieve into a large mixing bowl. Use the back of a ladle or a spatula to press the fruit through, discarding the seeds for a silky finish.

  6. 6

    Whisk the cooled keto syrup into the strained raspberry purée until the mixture is well-incorporated and vibrant in color.

  7. 7

    Cover the bowl with plastic wrap and refrigerate the mixture for at least 3-4 hours, or until it is thoroughly chilled (below 40°F/4°C).

  8. 8

    Once chilled, give the mixture a quick whisk. Turn on your ice cream maker and pour the raspberry base into the frozen canister while the machine is running.

  9. 9

    Churn the sorbet according to the manufacturer's instructions, usually about 15-20 minutes, until it reaches the consistency of a thick slush or soft-serve.

  10. 10

    Transfer the churned sorbet into a chilled, airtight container. Smooth the top with a spatula.

  11. 11

    Press a piece of parchment paper or wax paper directly onto the surface of the sorbet to prevent ice crystals from forming, then seal the lid tightly.

  12. 12

    Freeze for at least 4-6 hours to allow the sorbet to 'ripen' and firm up to a perfect scoopable consistency.

  13. 13

    Remove the sorbet from the freezer 5-10 minutes before serving to let it soften slightly at room temperature for the best flavor release.

💡 Chef's Tips

Use Allulose if possible; it behaves most like sugar and keeps the sorbet soft whereas Erythritol can sometimes feel grainy. Always strain your purée; raspberry seeds are small and can ruin the luxurious mouthfeel of a professional sorbet. Ensure your raspberry base is ice-cold before churning; if it's even slightly warm, it won't aerate properly in the ice cream maker. If you don't have an ice cream maker, pour the mixture into a shallow pan and whisk every 30 minutes for 3 hours to break up ice crystals. Taste your purée before chilling; if the berries are particularly tart, you may need an extra tablespoon of sweetener.

🍽️ Serving Suggestions

Serve in chilled glass coupes with a few fresh berries and a sprig of mint for a classic look. Pair with a crisp, dry Keto-friendly sparkling wine or Prosecco for a refreshing float. Top with a dollop of unsweetened whipped mascarpone for a creamy, high-fat keto contrast. Serve alongside a low-carb almond flour shortbread cookie for a delightful textural play. Drizzle with a tiny amount of sugar-free dark chocolate ganache for a 'Raspberry Truffle' experience.
