This is Su filindeu (thread of gods), a pasta so difficult to prepare that only three women of a single Sardinian family know how to make it
The ingredients are simple: semolina wheat, water, and salt. The serving preparation is similarly uncomplicated: gamey mutton broth and a helping of tangy pecorino cheese. Making the pasta, however, is nearly impossible. Engineers from the Barilla pasta company attempted, unsuccessfully, to build a machine that could reproduce the technique. Celebrity chef Jamie Oliver also visited Sardinia in hopes of mastering the elusive noodle. After two hours, he gave up.
