Yeah... you can pretty much use anything you want as the filling... I've got a @dtube video up where I make a dessert braai pie too if you're interested.

Re the "braai baskets/grid thingies":
We call them Toeknyp Roosters (aka "fold-up grids" - I don't think they even have a name in English :P).
Did you eventually find one and/or what did you use?

We normally go compete BBQ in The Jack and World Food Champs in the States every year, and would have gladly brought one with me... but this year, we're inviting the American teams to come compete here in SA instead. I can send one back with one of them if you'd like? Unfortunately that's only happening in September though.
