Granite countertop instead of marble slab for candy making.
I'm making fudge, peanut brittle and other things for Christmas this year. I know a marble would ideal, but I have a granite counter top. Am I risking ruining my granite because it may be a little more porous than marble. Will the temperature of the candy being poured onto my granite ruin it?
Basically I am paranoid of wrecking my nice granite. Am I crazy?
Ok , now I'm confused. I have done more research since my post and it seems like some granite companies advertise that thier Granite is ideal for candy making. The reason I don't go and buy a piece of marble is a live in a little condo in the city and don't usually buy unitaskers.
Granite is *less* porous than marble, relatively speaking -- none of the stones are porous compared to materials like wood but marble stains because of it porosity. And all stone tops are cut very deep and, so temperature stable. I don't think you could damage it with sugar and I don't think there's any magic property to marble other than those it shares with other stones: smooth, non-porous and with relatively stable temperatures.
If you want to experiment first, go to a stone yard and ask for a scrap piece of granite. They've probably got some 12"x12" scraps on hand that they're not going to do anything with. They might charge you a couple bucks but you'd get to play with it and have piece of mind about using your own broad counter. I got one section of marble counter at baking height installed when we redid our kitchen. It's bliss! You'll love working directly on your counter too.
