01 - Combine heavy cream, whole milk, granulated sugar, and a pinch of salt in a medium saucepan. Heat over medium, stirring occasionally, until the sugar is fully dissolved and the mixture is steaming hot. Do not allow it to boil.
02 - In a separate mixing bowl, lightly whisk the egg yolks until they are smooth and slightly pale in color.
03 - Gradually pour about 1 cup of the hot cream mixture into the whisked yolks in a slow, steady stream, whisking constantly. This gradual tempering prevents the yolks 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 170°F to 175°F.
05 - Remove the saucepan from heat and stir in the pure vanilla extract until fully 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 tightly and refrigerate for at least 4 hours or overnight for best results.
07 - Pour the thoroughly chilled custard into an ice cream maker and churn according to the manufacturer's instructions until the mixture reaches a thick, creamy, soft-serve consistency.
08 - Transfer the churned ice cream into a freezer-safe container, smooth the top, cover tightly, and freeze for at least 2 hours before scooping and serving.
