Irish Cream Crème Brûlée

Preheat the oven to 300 degrees F (150 degrees C). Place 6 ramekins on a towel set in a roasting pan at least 3 inches deep.

Stir together cream and sugar in a saucepan over medium heat, and cook until very hot, stirring until the sugar dissolves. Whisk together egg yolks, vanilla, and Irish cream until combined. Slowly add 1/3 of the hot cream, whisking it in 2 tablespoons at a time until incorporated. Once you have incorporated 1/3 of the cream, you can stir in the remaining hot cream without fear of the mixture curdling.

Pour custard into the ramekins, then fill roasting pan with boiling hot water to come halfway up the sides of the ramekins. Bake in preheated oven until set, 50 to 60 minutes.
