01 - In a saucepan, combine diced pineapple, granulated sugar, and lemon juice. Cook over medium heat for 5 minutes, stirring frequently, until the pineapple softens and sugar is fully dissolved. Remove from heat and let the mixture cool to room temperature.
02 - Transfer the cooled pineapple mixture to a blender or food processor. Blend until the mixture is completely smooth.
03 - In a large bowl, whisk together heavy cream, whole milk, vanilla extract, and salt until well incorporated. Gently stir in the pineapple puree until evenly combined.
04 - Cover the bowl and chill the mixture in the refrigerator for at least 2 hours for optimal flavor and consistency.
05 - Pour the chilled mixture into an ice cream maker and churn according to the manufacturer’s instructions, typically for 20 to 30 minutes, until the texture becomes thick and creamy.
06 - Transfer the churned ice cream to a freezer-safe container. Cover securely and freeze for a minimum of 4 hours, or until firm.
07 - Remove the ice cream from the freezer and allow it to rest at room temperature for 5 minutes before scooping and serving.
