I usually do about 3/4 block of platistowe (I think that's what it's called...) cooking choc and about 80ml cream - adjust the cream to suit the consistency you're after. I cheat and melt it in a saucepan then pour into the fondue set. Then I put a variety of things out for people to dip - bannana, strawberries, apple (you'd be surprised!), honeycomb... I'm sure I have an official receipe somewhere for the choc one but it's pretty simple. Also tastes great warm on ice cream
