01 - Combine pineapple, granulated sugar, and lemon juice in a saucepan. Cook over medium heat for 5 minutes until pineapple softens and sugar dissolves. Remove from heat and allow 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, pure vanilla extract, and salt until well combined.
04 - Stir the pineapple puree into the cream mixture. Cover and refrigerate for a minimum of 2 hours until thoroughly chilled.
05 - Pour the chilled mixture into an ice cream maker and churn following the manufacturer’s instructions, typically 20 to 30 minutes, until the texture is thick and creamy.
06 - Transfer the churned ice cream to a freezer-safe container, cover, and freeze for at least 4 hours or until firm.
07 - Allow the ice cream to sit at room temperature for 5 minutes to soften slightly before scooping and serving.
