'‘Amateur historians have often credited Thomas Jefferson with introducing macaroni and cheese to the United States. That probably isn’t true, but he did help make it popular. He dined on the dish during his time in Italy; he loved it so much that he brought a pasta maker back with him to the U.S. and served the dish at the White House in 1802. Mary Rudolph, who took over hostess duties at the White House when Jefferson’s wife died, included a macaroni recipe that with Parmesan cheese in her 1824 cookbook, “The Virginia Housewife.”’
Trying to find out when Mac and Cheese became big in Scotland but it keeps jut referring me to the macaroni pie
