making your own candy this holiday season to give as gifts or to keep for yourself, you may be working with fondant or tempering chocolate. If so, you're going to need a marble slab. Marble surfaces are useful for working with certain types of food because they stay cool - if you place one in the fridge, it will hold the cold temperature for a few hours. When hot candy is poured on a marble slab, it cools more quickly and this makes it easier to work with.
You can also use the marble tiles for working with pastry or serving cheese on.
