The Frugal Gourmet Cooks American
by Jeff Smith
Our real American foods have come from our soil and have been used by many groups— those who already lived here and those who have come here to live. The Native Americans already had developed an interesting cuisine using the abundant foods that were so prevalent.
The influence that the English had upon our national eating habits is easy to see. They were a tough lot, those English, and they ate in a tough manner. They wiped theft mouths on the tablecloth, if there happened to be one, and they ate until you would expect them to burst. European travelers to this country in those days were most often shocked by American eating habits, which included too much fat and too much salt and too much liquor. Not much has changed! And, the Revolutionists refused to use the fork since it marked them as Europeans. The fork was not absolutely common on the American dinner table until about the time of the Civil War, the 1860s. Those English were a tough lot.
Other immigrant groups added their own touches to the preparation of our New World food products. The groups that came still have a special sense of self-identity through their ancestral heritage, but they see themselves as Americans. This special self-identity through your ancestors who came from other lands was supposed to disappear in this country. The term melting pot was first used in reference to America in the late 1700s, so this belief that we would all become the same has been with us for a long time. Thank goodness it has never worked. The various immigrant groups continue to add flavor to the pot, all right, but you can pick out the individual flavors easily.
The largest ancestry group in America is the English. There are more people in America who claim to have come from English blood than there are in England. But is their food English Thanks be to God, it is not! It is American. The second largest group is the Germans, then the Irish, the Afro-Americans, the French, the Italians, the Scottish, and the Polish. The Mexican and American Indian groups are all smaller than any of the above, though they were the original cooks in this country.

A．English people had bad table manners.

B．American food was exclusively unique in its flavors and varieties.

C．American diet contained a lot of fat, salt and liquor.

D．Europeans were not at all accustomed to the American way of eating.
