12 ounces
Guinness stout
2 cups
heavy cream
2 cups
whole milk
3/4 cup
granulated sugar
1 vanilla
bean, split in half lengthwise
6 egg
yolks
|
In a large saucepan,
simmer the Guinness until reduced by 3/4 in volume, about 8 minutes. Combine
the cream, milk, and sugar in a medium, heavy saucepan. Scrape the seeds
from the vanilla bean into the pan and add the vanilla bean halves. Bring
to a gentle boil over medium heat. Remove from the heat. |
Beat the egg
yolks in a medium bowl. Whisk 1 cup of the hot cream into the egg yolks.
Gradually add the egg mixture in a slow, steady stream, to the hot cream.
Cook over medium-low heat, stirring occasionally, until the mixture thickens
enough to coat the back of a spoon and reaches 170 degrees F. on an instant-read
thermometer, about 5 minutes. |
Remove from
the heat and strain through a fine mesh strainer into a clean container.
Cover with plastic wrap, pressing down against the surface to keep a skin
from forming. Chill in the refrigerator for 2 hours. |
Remove from
refrigerator and add the Guinness reduction, whisking until well blended.
Pour into the bowl of an ice cream machine and freeze according to the
manufacturer's instructions. Transfer to an airtight container and freeze
until ready to serve. |
