Beat the heat with a refreshing scoop of homemade lemon curd ice cream. This creamy and tangy frozen treat is perfect for lemon lovers. Start by making a custard base using egg yolks, sugar, milk, and heavy cream. Cook the mixture over low heat until thickened. Remove from heat and stir in the lemon curd until well combined. Allow the mixture to cool completely, then churn it in an ice cream maker according to the manufacturer's instructions. Transfer the ice cream to a container and freeze until firm. Serve the lemon curd ice cream in cones or bowls for a delightful summer dessert.
