01 - In a saucepan, combine heavy cream, whole milk, granulated sugar, and a pinch of salt. Heat over medium, stirring occasionally, until the sugar fully dissolves and the mixture is steaming hot. Do not allow it to boil.
02 - In a separate mixing bowl, lightly whisk the egg yolks until smooth and slightly pale.
03 - Slowly pour about 1 cup of the hot cream mixture into the yolks in a thin, steady stream while whisking constantly. This gradual tempering prevents the eggs from scrambling.
04 - Pour the tempered yolk mixture back into the saucepan. Stir continuously over medium-low heat until the custard thickens slightly and evenly coats the back of a spoon, reaching an internal temperature of 170°F to 175°F.
05 - Remove the saucepan from heat and stir in the pure vanilla extract until fully incorporated.
06 - Pour the custard through a fine mesh sieve into a clean bowl to remove any cooked egg bits. Allow it to cool to room temperature, then cover tightly and refrigerate for at least 4 hours or overnight.
07 - Once thoroughly chilled, pour the custard into an ice cream maker and churn following the manufacturer's instructions until the mixture becomes thick, creamy, and softly frozen.
08 - Transfer the churned ice cream into a freezer-safe container, press a sheet of plastic wrap directly against the surface, cover with a lid, and freeze for at least 2 hours until firm enough to scoop.
