01 - In a saucepan, combine the heavy cream, whole milk, granulated sugar, and salt. Heat over medium, stirring occasionally, until the mixture is hot and the sugar has fully dissolved. Do not allow the mixture to boil.
02 - In a separate mixing bowl, lightly whisk the egg yolks until they are smooth and slightly pale in color.
03 - Slowly pour about 1 cup of the hot cream mixture into the whisked egg yolks, whisking constantly to gradually raise the temperature of the yolks without scrambling them.
04 - Pour the tempered yolk mixture back into the saucepan with the remaining cream. Stir continuously over medium-low heat until the custard thickens slightly and coats the back of a spoon, reaching an internal temperature of 170–175°F.
05 - Remove the saucepan from heat. Stir in the pure vanilla extract until evenly incorporated throughout the custard.
06 - Strain the custard through a fine mesh sieve into a clean bowl to remove any cooked egg bits. Allow the custard to cool to room temperature, then cover tightly and refrigerate for at least 4 hours or overnight.
07 - Once the custard is thoroughly chilled, pour it into an ice cream maker and churn according to the manufacturer's instructions until the mixture is thick, creamy, and has the consistency of soft-serve ice cream.
08 - Transfer the churned ice cream into a freezer-safe container, cover securely, and freeze for at least 2 hours before serving to allow the texture to firm up.
