Simple Creme Brulee Pie

My husband loves creme brulee! He orders it every time he sees it on a menu! I've been thinking of making creme brulee at home, but it requires the use of a small blow torch (kitchen size) to crystallize the sugar topping! I don't want to invest money in a kitchen torch, that will probably only be used to make creme brulee! Then I saw this recipe and knew I had to try it...
