Marble square
 

I've been playing with making chocolate truffles here
recently and I've had a lot of fun with them and the
family and people at work like them. I've been using
variations on the standard semisweet chocolate chips
and cream. I'd like to try a non-chocolate fondant
with a sugar base, but it says to pour it out on a
marble slab and work it. Do I really need a marble
top or something similar to do a sugar-based fondant?
If yes, where can I get one online? If no, what do I
do instead?

Thank you, Michael
