Bombolone

A bombolone is an Italian filled doughnut (similar to a Berliner, pączek, etc.), eaten as a snack food and dessert. The pastry's name is etymologically related to bomba (lit. 'bomb'), and the same type of pastry is also called "bomba" (pl.: bombe) in some regions of Italy. The etymological connection is probably due to the resemblance to a grenade or old-fashioned bomb and may today possibly also be regarded as a reference to the high calorie density of this pastry (i.e., a "calorie bomb").[original research?] While bomboloni may be primarily connected to Tuscany, they are traditional to other regions of Italy, although with slight variations on the recipe. In those areas that used to be under Austrian rule, such as Trentino-Alto Adige, Veneto and Friuli-Venezia Giulia, the tradition of bomboloni is believed to have originated from that of Austrian "krapfen" (i.e., Berliner), and the recipe includes eggs, which are not found in the Tuscan variety. Pasticcerie sometimes have handwritten signs for them, and food writer Emily Wise wrote that visitors might not be as taken with hot filled doughnuts in an area with wild boar salami and sandwiches with truffle oil on offer, but that residents of Tuscany enjoy them even at the beach. They are also sold from carts on the beach and are a bit distinct from the filled doughnuts in other countries by having the filling put in from the top, where it is sometimes visible, rather than injected from the side.
