They were employed in manual labor or factory work but it is because of them that dishes like spaghetti with meatballs, New York–style pizza, calzones, and baked ziti exist, and Americans of today are very familiar with semolina based pasta noodles. Their native cuisine had less of an emphasis on meat, as evidenced by dishes they introduced like pasta e fagioli and minestrone, but the dishes they created in America often piled it on as a sign of wealth and newfound prosperity since for the first time even cheap cuts of it were affordable: the American recipe for lasagna is proof of this, as mostly it is derived from the Neapolitan version of the dish with large amounts of meat and cheese. New York–style hot dogs came about with German speaking emigrants from Austria and Germany, particularly with the frankfurter sausage and the smaller wiener sausage; Jews would also contribute here by introducing the kosher version of these sausages, made of beef rather than pork. Today, the New York–style hot dog with sauerkraut, mustard, and the optional cucumber pickle relish is such a part of the local fabric, that it is one of the favorite comestibles of New York City and both the pork and the beef versions are beloved. Hot dogs are a typical street food sold year round in all by the most inclement weather from thousands of pushcarts. As with all other stadiums in Major League Baseball they are an essential for New York Yankees and the New York Mets games though it is the local style of preparation that predominates without exception. Hot dogs are also the focus of a televised eating contest on the Fourth of July in Coney Island, at Nathan's Famous, one of the earliest hot dog stands opened in the United States in 1916 by Nathan Handwerker, a Jewish man who emigrated from what is now Ukraine in 1912 and whose influence is felt today around the world: hot dogs are a staple of amusement parks 100 years later. A summertime treat, Italian ice, began its life as a sweeter adaptation of the Sicilain granita that was strictly lemon flavored and brought to New York and Philadelphia. Its Hispanic counterpart, piragua, is a common and evolving shaved ice treat brought to New York City by Puerto Ricans in the 1930s. Unlike the original dish which included flavors like tamarind, mango, coconut, piragua is evolving to include flavors like grape and cherry, fruits which are impossible to grow in the tropical Puerto Rican climate and get exported back to the island from New York.
