Today I finally made it. It was a success from the get-go, easy and as good, if not better, than any I've had in any restaurant. You can find the recipe here. Buy the torch (and some butane) and have at it! It is really a great special dessert for a nice dinner, and not that hard. Just leave some time for the cooling and chilling.
It's not a low calorie dessert, though. I figure it at about 900 calories a portion! So save it for a special occasion, or enjoy it on an otherwise low-calorie day.
