01 - In a saucepan, combine diced pineapple, granulated sugar, and lemon juice. Cook over medium heat for 5 minutes until the pineapple softens and sugar is dissolved. Allow mixture to cool to room temperature.
02 - Transfer the cooled pineapple mixture to a blender or food processor and blend until completely smooth.
03 - In a large bowl, whisk together heavy cream, whole milk, vanilla extract, and salt until evenly mixed. Gently fold in the blended pineapple puree.
04 - Cover the bowl and refrigerate for a minimum of 2 hours until thoroughly chilled.
05 - Pour the chilled mixture into an ice cream maker. Churn according to manufacturer’s instructions, typically 20 to 30 minutes, until a thick and creamy consistency is achieved.
06 - Transfer churned ice cream to a freezer-safe container. Cover tightly and freeze for at least 4 hours or until the texture is firm.
07 - Let the ice cream stand at room temperature for 5 minutes before scooping. Serve immediately.
