This is something I do all the time, but have never spoken of. Why? Because, well, it's embarrassing. But in the name of good Chow, I shall let you in on my dirty little secret.
I take a few store-bought pudding cups (ie. vanilla snack-pak) and empty them into a ramekin. Smooth them out, and top them with raw / demarara / brown sugar, and torch them a la creme brulee (or use the oven broiler).
Voila! Instant creme brulee. If like me, you're in Ontario, I suggest using the President's Choice Vanilla Bean pudding as your base. It's very tasty and makes for a very successful creme brulee-esque experience. :)
