I went on my honeymoon to Italy this September and we made a stop at Carrara, which is where the white marble comes from. I bought a Carrara marble rolling pin there in a gift shop, which I had been hunting for, for years. This was my first time using my new rolling pin. I love it! The heavy marble really weighed down the dough, which made it easier to work the dough.
I got the recipe from Sally's Baking Addiction for both the sugar cookies and royal icing. Link here.
Let me know if you try (or tried) this recipe!
