I haven't seen one of these yet that doesn't make me want to go 'ew'. The Banana Brulée is strange because you use the warm Ambrosia custard and then cool. Why not just suggest you by the cold tinned/cartoned Ambrosia custard instead?
And that pasta bake hell that El Tel (I think it's him) suggests looks like something a student would turn their nose up at.
I see we have a fizzy jelly one being advertised on DiS. That sounds somewhat okay.
