12 large yolks, pasteurized if you need peace of mind
1 pound sugar
1 teaspoon freshly grated nutmeg
1 pint half-and-half
1 pint whole milk
1 pint heavy cream
1 cup (8oz) Jamaican rum
1 cup (8oz) cognac
1 cup (8oz) bourbon
1/4 teaspoon kosher salt
Directions
Beat the yolks with the sugar and nutmeg in a large mixing bowl until the mixture lightens in color and falls off the whisk in a solid ribbon.
Combine dairy, booze, and salt in a second bowl or pitcher and then slowly beat into the egg mixture.
Move to a large glass jar (or a couple of smaller ones) and store in the fridge for a minimum of 2 weeks. A month would be better, and 2 better still. In fact, there’s nothing that says you couldn’t age it a year, but I’ve just never been able to wait that long. And yes, you can also drink it right away.
Serve in mugs or cups topped with a little extra nutmeg grated on top.
