It appears that many people are having trouble with this recipe. As I have always had great success with it, I can only assume our differences lie in the quality of the whipped cream available 'here' as opposed to other places. I get fresh whipping cream - not the ultra-pasteurised stuff, so this is probably where our differences lie. If you have a source for 'real' cream, and not cream that has been radiated, I'm sure you'll enjoy the same success with this recipe. This makes enough to ice a 2-layer cake - provided you can stop yourself from eating it up right out of the bowl (and the beaters...and the spatula...)
