Simple Vanilla Ice Cream

Preparation

1. Step 1

   Put 2 cups cream, half-and-half or milk, the sugar and salt in a saucepan over medium-low heat. If using a vanilla bean, split in half lengthwise and scrape seeds into liquid, then add pod. Cook until mixture begins to steam.

2. Step 2

   In a bowl, blend cornstarch and remaining cream, half-and-half or milk; there should be no lumps. Remove bean pod from pot and discard. Add cornstarch mixture to pot. Cook, stirring, until it starts to thicken and barely reaches a boil, about 5 minutes. Immediately reduce heat to very low and stir for 5 minutes or so until thick. Stir in vanilla extract, if using.

3. Step 3

   If mixture has lumps, strain it into a bowl. Chill until cool, a couple of hours (you can skip this step if you have a machine with a built-in freezer). When cool or if there are no lumps, pour into an ice cream machine and freeze according to the manufacturer's instructions.
