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 they are smooth and slightly pale in color.
03 - While whisking the yolks constantly, slowly pour about 1 cup of the hot cream mixture into the bowl. This gradual addition prevents the eggs from scrambling.
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 the 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.
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 a soft-serve consistency.
08 - Transfer the churned ice cream into a freezer-safe container, cover securely, and freeze for at least 2 hours to firm up before scooping and serving.
