1 vanilla bean, split lengthwise and scraped, seeds reserved
9 egg yolks
Instructions
In a medium saucepan, combine half-and-half, sugar, vanilla extract, salt, vanilla bean, and reserved vanilla seeds. Bring mixture to a boil over medium-high heat, whisking often, until sugar is dissolved. Remove mixture from heat.
In a medium bowl, whisk egg yolks until smooth. Using a ladle, pour 1 cup hot half-and-half mixture in a slow, steady stream into yolks, whisking constantly. Add another cup half-and-half mixture, whisking to combine. Transfer mixture back to pan, whisking to combine. Cook over medium heat, stirring constantly, until temperature registers 170° on an instant-read thermometer or mixture is thick enough to coat the back of a wooden spoon. Strain mixture through a fine-mesh sieve* into a stainless-steel bowl set in an ice-water bath. Let cool completely, stirring often.
Transfer mixture to an airtight container, and refrigerate for at least 2 hours.
Using an ice-cream maker, freeze half-and-half mixture according to manufacturer’s instructions. Transfer ice cream to a freezer-safe container. Freeze for at least 4 hours before serving. Ice cream can be stored, frozen, for up to 2 weeks.
Notes
*You may substitute cheesecloth for a fine-mesh sieve, if desired.
