Michetta

Michetta or rosetta (Italian for 'little rose', used in the rest of the country) is an Italian white bread, recognizable by its bulged shape. Michetta is a variation of the Austrian Kaisersemmel brought to Milan in the 19th century during the Austrian rule. Functionaries of the Austrian empire introduced a number of food products, including the Kaisersemmel, a type of bread with segments resembling a small rose. However, due to the higher humidity, the michetta produced in Milan is made with a modified recipe, and only lasts one day.
