Are you referring to pudding as the British refer to dessert?

I'm guessing you mean this type of fruit pudding? http://en.wikipedia.org/wiki/Fruit_pudding

I'm not really familiar with cooking a pudding like this, but I'd guess you'd want to make sure it was pretty compact to start with, then fry it in plenty of butter so it doesn't stick. And try not to move it around much, just flip it gently. Good luck!
