Chill the ice cream maker bowl:
At least 12 hours before making the ice cream, freeze the bowl of your ice cream maker. It needs to be fully chilled for the ice cream to firm up properly.
Prepare the ice cream base:
In a medium saucepan, combine 1½ cups of heavy cream, 1½ cups of whole milk, ⅔ cup of cane sugar, 2 teaspoons of vanilla extract, and ⅛ teaspoon of sea salt. Heat the mixture over medium-low heat, whisking frequently for 5 minutes, until the sugar is completely dissolved and the mixture is warmed through. Remove from heat.
Cool the ice cream base:
Transfer the warm mixture into a heatproof bowl, cover, and let it chill for at least 2 hours or overnight in the refrigerator.
Churn the ice cream:
Once the ice cream base is well-chilled, whisk it to ensure it’s smooth. Pour it into your ice cream maker and churn according to the manufacturer’s instructions. This typically takes 20 to 30 minutes.
Freeze the ice cream:
After churning, the ice cream will be soft-serve consistency. For firmer ice cream, transfer it to an airtight container and freeze for 2 to 4 hours.
Serve and enjoy:
Scoop the chilled ice cream into bowls or cones and enjoy! If stored, allow it to sit at room temperature for a few minutes to soften before scooping.
