Prepare Your Chiller: At least 12 hours before you plan to make your ice cream, pop the bowl of your ice cream maker into the freezer. It needs to be thoroughly chilled to work its magic!
Whip Up the Base: In a medium saucepan, combine the heavy cream, whole milk, cane sugar, vanilla extract, and sea salt. Gently warm this mixture over medium-low heat for about 5 minutes, whisking frequently. You'll know it's ready when the sugar has completely dissolved and the mixture feels warm to the touch.
Chill Out: Pour the warm ice cream base into a heatproof bowl. Cover it and place it in the refrigerator to chill for at least 2 hours, or even better, overnight. This crucial step ensures a wonderfully creamy texture.
Churn to Perfection: Once your base is perfectly chilled, give it a good whisk, then transfer it to your pre-frozen ice cream maker bowl. Churn according to your manufacturer's instructions, typically for 20 to 30 minutes, until it reaches a soft-serve consistency.
Firm Up (Optional): If you prefer a firmer, scoopable ice cream, transfer it from the ice cream maker into an airtight container. Freeze for an additional 2 to 4 hours.
Enjoy & Store: Serve immediately for a soft, delicious treat, or freeze for a firmer texture. Store any leftovers in an airtight container in the freezer for up to one month. If it gets too firm, just let it sit at room temperature for a few minutes before scooping!
