01 - Combine pineapple, granulated sugar, and lemon juice in a saucepan. Cook over medium heat for 5 minutes until the pineapple is softened and sugar has dissolved. Allow the mixture to cool to room temperature.
02 - Transfer the cooled pineapple mixture to a blender or food processor. Puree until completely smooth.
03 - In a large bowl, whisk together heavy cream, whole milk, vanilla extract, and salt. Incorporate the pineapple puree and stir until fully combined.
04 - Cover the bowl and refrigerate the mixture for a minimum of 2 hours.
05 - Pour the thoroughly chilled mixture into an ice cream maker and churn according to manufacturer’s directions, typically 20 to 30 minutes, until a thick, creamy consistency is achieved.
06 - Transfer the churned mixture to a freezer-safe container, cover securely, and freeze for at least 4 hours until the ice cream is firm.
07 - Before serving, let the ice cream rest at room temperature for 5 minutes to ease scooping.
