01 - Combine diced pineapple, granulated sugar, and lemon juice in a saucepan. Cook over medium heat for 5 minutes until pineapple softens and sugar dissolves. Allow to cool to room temperature.
02 - Puree the cooled pineapple mixture in a blender or food processor until completely smooth.
03 - In a large bowl, whisk together heavy cream, whole milk, vanilla extract, and salt. Stir in the pineapple puree until fully incorporated.
04 - Cover the bowl and refrigerate for at least 2 hours to ensure the mixture is thoroughly chilled.
05 - Pour the chilled mixture into an ice cream maker and churn according to manufacturer’s directions, typically 20 to 30 minutes, until thick and creamy.
06 - Transfer the churned ice cream into a freezer-safe container, cover, and freeze for at least 4 hours or until solid.
07 - Let the ice cream sit at room temperature for 5 minutes before scooping for optimal texture.
