漢堡包的洗底之路

In the debate about whether the hamburger originated in western New York, Connecticut, Wisconsin, Ohio, Oklahoma, or Texas—claims often built on unsubstantiated assertions and/or proud family members’ testimony—one point is clear: Somewhere in the United States the hamburger was born.
(Adams,2018,p.18)

There were some jobs that it only paid to do once in a long time, and among these was the cleaning out of the waste barrels. Every spring they did it; and in the barrels would be dirt and rust and old nails and stale water—and cart load after cart load of it would be taken up and dumped in to the hoppers with fresh meat, and sent out to the public’s breakfast.
(Sinclair, 1973. p.162)

I aimed at the public's heart, and by accident I hit it in the stomach.
——Upton Sinclair Jr.

When the word “hamburger” is mentioned, one immediately thinks of the circus...or [a] dirty, dingy, ill-lighted hole-in-the wall, down in the lower districts of the city. The day of the dirty, greasy hamburger is past. No more shall we have to taste the hamburger at circuses or carnivals only, for a new system has arisen, the “White Castle System”
(Hogan, 1997, p.31)
