Step 1: Combine heavy cream, whole milk, granulated sugar, pure vanilla extract, and salt in a large mixing bowl. Whisk until the sugar is completely dissolved. If using, stir in vanilla bean paste or vanilla bean seeds for an intensified flavor.
Step 2: Cover the bowl tightly with plastic wrap and refrigerate the mixture for at least 2 hours, or until it is thoroughly chilled. This is crucial for achieving the best creamy texture.
Step 3: If using an ice cream maker, pour the chilled mixture into the machine and churn according to the manufacturer’s instructions, typically 20-25 minutes, until it reaches a soft-serve consistency. If you don’t have an ice cream maker, pour the mixture into a shallow freezer-safe container. Place it in the freezer and stir every 30 minutes with a fork, scraping down the sides, for 3-4 hours, until it’s frozen and creamy.
Step 4: Transfer the soft ice cream to an airtight freezer-safe container. Smooth the top with a spatula and press a piece of plastic wrap directly onto the surface to prevent ice crystals. Cover with a lid.
Step 5: Freeze for at least 4 hours, or until the ice cream is firm. Before serving, let it sit at room temperature for 5-10 minutes to soften slightly, then scoop and enjoy your homemade treat!
