This homemade Blueberry Lemon Ice Cream brings together the sweet, fruity flavor of blueberries and the tangy zing of lemon for a refreshing dessert. The creamy custard base combined with the vibrant fruit puree makes each bite an indulgent treat. Perfect for summer days or any occasion, this ice cream is easy to make with just a few ingredients and an ice cream maker.
In a medium saucepan, combine blueberries, sugar, and lemon juice. Cook over medium heat until the blueberries soften and release their juices, about 5-7 minutes.Mash them slightly, then strain the mixture to remove seeds and skins. Set aside to cool.
Prepare the Custard Base
In a separate bowl, whisk together egg yolks and sugar until thick and pale. In a saucepan, heat the heavy cream and milk over medium heat until warm, but not boiling. Slowly pour the warm cream mixture into the egg yolks, whisking constantly to temper the eggs. Return the mixture to the saucepan and cook over low heat, stirring until it thickens enough to coat the back of a spoon.
Combine the Custard and Blueberry Puree
Once the custard has thickened, remove it from heat. Stir in the blueberry puree, lemon zest, and vanilla extract (if using). Allow the mixture to cool to room temperature, then refrigerate for 4 hours or overnight.
Churn the Ice Cream
Once chilled, pour the mixture into an ice cream maker and churn according to the manufacturer’s instructions, usually 20-25 minutes.
Freeze to Firm Up
Transfer the ice cream to a freezer-safe container and freeze for at least 4 hours, or until firm.
Notes
Chilling is Key: For the smoothest texture, ensure the mixture is well-chilled before churning. This helps reduce ice crystals and results in a creamier ice cream.
Lemon Zest: Be sure to use fresh lemon zest for the best flavor. It enhances the citrusy tang of the ice cream.
Consistency: If you prefer a softer ice cream, you can enjoy it right after churning. For a firmer texture, let it freeze for at least 4 hours.
