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 hot. Do not allow it to boil.
02 - In a separate mixing bowl, lightly whisk the egg yolks until smooth.
03 - Gradually pour about 1 cup of the hot cream mixture into the yolks while whisking constantly. This gradual addition prevents the eggs from scrambling.
04 - Return the tempered yolk mixture to the saucepan. Stir continuously over medium-low heat until the custard thickens slightly and coats the back of a spoon, reaching 170–175°F.
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 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 it reaches a thick, creamy consistency.
08 - Transfer the churned ice cream into a freezer-safe container, cover tightly, and freeze for at least 2 hours before serving.
