I'm making more and more bread and home-made pasta. I'd like to buy a marble pastry board for mixing/kneading/rolling/etc. But none of the ones I'm finding in stores seem big enough.
Can I just go down to the kitchen section of my local home store and buy a big piece of marble counter-top? Or is that marble treated? Or is that marble not treated and marble pastry boards are treated?
And help would be greatly appreciated.
