Ingredients:
- 2 cups (300g) fresh blueberries
- 1/4 cup (50g) granulated sugar
- 1 tbsp (15ml) fresh lime juice
- 2 cups (480ml) heavy cream, chilled
- 1 cup (240ml) whole milk, chilled
- 3/4 cup (150g) granulated sugar
- 1 tbsp (6g) lime zest, finely grated
- 1 tsp (5ml) vanilla extract
- 1 pinch (1g) salt
Instructions:
- Combine blueberries, 1/4 cup sugar, and lime juice in a saucepan over medium heat. Stir occasionally for 8–10 minutes until the berries burst and the liquid thickens into a syrupy consistency.
- Pour the blueberry mixture into a blender and pulse until smooth.
- Transfer the puree to a bowl and refrigerate until completely cold.
- In a large bowl, whisk together the chilled heavy cream, whole milk, 3/4 cup sugar, lime zest, vanilla, and salt.
- Slowly stir the chilled blueberry-lime reduction into the cream base until the mixture is a deep purple color.
- Let the base sit in the fridge for at least 30 minutes to allow the lime zest to infuse.
- Pour the mixture into an ice cream maker and churn according to manufacturer's directions until it reaches a soft-serve consistency (usually 20–25 minutes).
- Transfer the ice cream to a freezer-safe container, press plastic wrap directly onto the surface, and freeze for at least 4 hours until firm.
