Grissini

Breadsticks, also known as grissini , are generally pencil-sized sticks of crisp, dry baked bread that originated in the Italian city of Turin, Piedmont. It is believed that the breadstick originated in 1643, when a Florentine abbot described a long-shaped and "bone-thin" bread being made in Lanzo Torinese, a town outside of Turin. Tradition states, however, that it originated in the region of Piedmont in the 17th century, invented by a baker called Antonio Brunero, from Turin. It was a food that was intended to be easier to digest for the Duke Victor Amadeus II of Savoy, who had digestive problems in his childhood.
