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 5 large egg yolks until they are smooth and slightly pale.
03 - Slowly pour about 1 cup of the hot cream mixture into the whisked egg yolks while whisking constantly. This gradual addition tempers the yolks and prevents them from scrambling.
04 - Pour the tempered yolk mixture back into the saucepan with the remaining cream base. 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 (76-80°C).
05 - Remove the saucepan from heat and stir in the pure vanilla extract until evenly 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 for best results.
07 - Once the custard is thoroughly chilled, pour it into an ice cream maker and churn according to the manufacturer's instructions until it reaches a thick, creamy consistency.
08 - Transfer the churned ice cream into a freezer-safe container, cover securely, and freeze for at least 2 hours before scooping and serving.
