These golden feather-light semolina flatbread crackers are alluringly crispy and thin. The aroma of freshly baked bread and toasted flavor are enhanced by a drizzle of olive oil and a sprinkle of salt. This style of flatbread has ancient origins and has been a Sardinian specialty for thousands of years. Historically, it was a staple of shepherds who needed a shelf-stable bread to last through the long winters and transhumance. This variation, paper-thin with a drizzle of olive oil, is known as pane guttiau in Sardinian. It is enjoyed as a delicate and savory cracker that can pair with anything from olives to cheese and charcuterie. The poetic name of Pane di Musica evokes sheets of parchment used for notating music.
