01 - In a saucepan, combine the heavy cream, whole milk, granulated sugar, and a pinch of 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 loosened and smooth.
03 - Slowly pour about 1 cup of the hot cream mixture into the yolks while whisking constantly. This gradual addition tempers the yolks and prevents scrambling.
04 - Pour the tempered yolk mixture back into the saucepan, stirring continuously. Cook 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 and stir in the pure vanilla extract until evenly incorporated.
06 - Strain 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 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 thick, creamy, and softly frozen.
08 - Transfer the churned ice cream to a freezer-safe container, cover tightly, and freeze for at least 2 hours before serving to achieve a firm, scoopable consistency.
