When I heard about the paper-thin, unleavened, crisp bread that Sardinia is famous for, I instantly headed in that direction. The first night I was greeted with a big basket stacked with bread, the thinnest crispiest bread I'd ever seen. It was shiny with Sardinian olive oil and scattered with rosemary needles. Carta di musica, or music-paper bread, it gets its name from being so thin, you can read sheet music through it. To taste carta di musica, a trek to Sardinia may seem like a long way to go. So here is a recipe that I never dreamed would be so easy to reproduce at home.
