I like the subtle character that the butterscotch brings to the custard. Most Creme Brulee recipes use all heavy cream; this is somewhat lighter because of the use of half-and-half, but there's no mistaking that this is a rich, decadent dessert. This recipe does require a brulee torch to do properly, though I understand that it can be done by placing under your oven's broiler and carefully watching. You will need 4 ramekins, something that can withstand the cooking temperatures of an oven.
