The American president Thomas Jefferson encountered macaroni both in Paris and in northern Italy. He drew a sketch of the pasta and wrote detailed notes on the extrusion process. In 1793, he commissioned American ambassador to Paris William Short to purchase a machine for making it. Evidently, the machine was not suitable, as Jefferson later imported both macaroni and Parmesan cheese for his use at Monticello. In 1802, Jefferson served "a pie called macaroni" at a state dinner. The menu of the dinner was reported by Reverend Manasseh Cutler, who apparently was not fond of the cheesy macaroni dish. Nevertheless, since that time, baked macaroni and cheese has remained popular in the United States.
... A recipe called "macaroni and cheese" appeared in the 1824 cookbook The Virginia Housewife written by Mary Randolph. Randolph's recipe had three ingredients: macaroni, cheese, and butter, layered together and baked in a hot oven. The cookbook was the most influential cookbook of the 19th century, according to culinary historian Karen Hess. Similar recipes for macaroni and cheese occur in the 1852 Hand-book of Useful Arts, and the 1861 Godey's Lady's Book. By the mid-1880s, cookbooks as far west as Kansas and Festus, Missouri, included recipes for macaroni and cheese casseroles. Factory production of the main ingredients made the dish affordable, and recipes made it accessible, but not notably popular. As it became accessible to a broader section of society, macaroni and cheese lost its upper-class appeal.
