Required Equipment
Blender or Food Processor
This is essential for ensuring a smooth sorbet texture, especially if you’re using frozen lemon juice cubes.
Saucepan
Used to dissolve the sweetener into the lemon juice, creating a perfectly balanced flavor.
Fine Mesh Strainer
To remove any pulp or seeds for an ultra-smooth sorbet.
Freezer-Safe Container
A must for storing your sorbet and keeping it at the perfect consistency.
Ingredients & Substitutions
- 1 cup freshly squeezed lemon juice – Provides the vibrant citrus flavor. You can also use lime juice for a tangy twist.
- 1/2 cup keto-friendly sweetener – Such as allulose, erythritol, or monk fruit. Allulose works best as it dissolves easily and prevents iciness.
- 1 cup water – Helps blend everything smoothly.
- 1/2 tsp lemon zest – Adds an extra punch of lemon flavor.
- 1/4 tsp xanthan gum (optional) – Helps create a smoother texture and prevents ice crystals.
- 1/2 tsp vanilla extract (optional) – Enhances the overall flavor and balances the tartness.
How to Make Keto Lemon Sorbet
- Make the Lemon Syrup: In a small saucepan, heat the lemon juice, water, and sweetener over medium heat. Stir until the sweetener dissolves completely. Remove from heat and let it cool.
- Strain & Chill: Pour the mixture through a fine mesh strainer to remove pulp or seeds. Add lemon zest and vanilla extract (if using). Chill in the fridge for at least an hour.
- Blend & Freeze: Pour the chilled mixture into a blender, add xanthan gum (if using), and blend for a few seconds. Transfer to a freezer-safe container.
- Freeze & Stir: Freeze for about 3 hours, stirring every 30 minutes to break up ice crystals. If using an ice cream maker, follow the manufacturer’s instructions.
- Serve & Enjoy: Once the sorbet reaches your desired consistency, scoop and enjoy!
Tips for This Recipe
- Use Allulose for the Best Texture – It keeps the sorbet smooth and prevents it from becoming too icy.
- Chill the Mixture Before Freezing – This helps create a smoother consistency.
- Blend Before Freezing – This adds air to the sorbet, making it light and refreshing.
- Let It Sit Before Scooping – If too firm, let it sit at room temperature for a few minutes before serving.
Optional Additions
- Mint Leaves: Blend or garnish with fresh mint for an extra refreshing touch.
- Coconut Cream: For a creamy lemon sorbet, blend in 1/4 cup of coconut cream before freezing.
- Berry Swirl: Add a swirl of keto raspberry sauce for a fruity twist.
Serving Ideas
- As a Light Dessert: Perfect after a hearty keto meal.
- Paired with Keto Shortbread Cookies: For a delicious contrast of textures.
- In a Keto Lemon Float: Add a scoop to sparkling water for a fun summer drink.
Storage Recommendations
- Store in an airtight container in the freezer for up to 2 weeks.
- To prevent freezer burn, press a piece of parchment paper directly onto the surface.
- Allow it to sit at room temperature for 5-10 minutes before scooping for the best texture.
Frequently Asked Questions
Can I use bottled lemon juice?
Fresh lemon juice is best for flavor, but bottled can work in a pinch. Just make sure it’s 100% pure lemon juice without added sugars.
What’s the best sweetener for sorbet?
Allulose works best for texture, but monk fruit or erythritol can also be used. Just note that erythritol may create a slightly grainy texture.
How do I make it without an ice cream maker?
Simply freeze the mixture and stir every 30 minutes for a few hours to prevent large ice crystals.
