Also known as carta di musica (sheet music), this ancient Sardinian flatbread is famous for being paper-thin and incredibly crisp. It is a double-baked wonder: the first bake creates a soft, flexible wrap, while the second bake transforms it into a long-lasting, crunchy cracker that is perfect for dipping.
You can absolutely use a baking steel instead of a stone! Steels actually conduct heat more efficiently, which can help the bread puff up even faster. Just keep a close eye on it to prevent burning.
