In a mixing bowl, whisk together the heavy cream, whole milk, lemon curd, granulated sugar, vanilla extract, and salt until well combined and the sugar is dissolved.
Stir in the lemon zest for added flavor.
Pour the mixture into an ice cream maker and churn according to the manufacturer's instructions, usually about 20-25 minutes, until it reaches a soft-serve consistency.
Transfer the churned ice cream to an airtight container and freeze for at least 4 hours or until firm.
Scoop and serve the ice cream in bowls or cones. Enjoy!
