Pork Roll, Egg and Cheese
Four cuts in the edge of each slice, a hot dry pan, and a cheese slice laid on the meat rather than on the bread. Everything else about this sandwich is assembly.
The meat has a paper trail, and it runs through a federal court. In Taylor Provision Co. v. Gobel, 180 F. 938, decided on 15 August 1910 in the Circuit Court for the Eastern District of New York, Judge Chatfield set out the history as a finding of fact: the preparation "was known as 'Taylor's Prepared Ham,' but with the passage of the pure food law by the Congress of the United States it became necessary to change the label of this article," after which the company sold it "under the name of 'Taylor's Pork Roll,' or 'Trenton Pork Roll,' the preparation still being sold in cotton bags, and having red letters in outline printed upon the bags." The same company was in the New Jersey Court of Chancery a year later against another rival, in The Taylor Provision Company v. Andrew H. Edwards, 79 N.J. Eq. 142, decided 17 December 1911 by Vice-Chancellor Walker, arguing again over who could label a brand "pork roll". So the quarrel over the name is not a modern internet argument. It is litigation, it is more than a century old, and the federal Pure Food Act is the reason the word ham came off the label.
The newspapers fill in what the courts leave out, and they complicate the story everyone tells. The Burlington County Historical Society's digitised run of the Mount Holly papers — 1818 to 1960, searchable through Advantage Archives — shows the New Jersey Mirror advertising "PREPARED HAM, An entirely new article, for sale at the store of E. B. Murray & Co." on 25 January 1855, with no maker named. By 8 February 1905 a Mount Holly grocer is listing "The Taylor Ham, 16c. lb."; on 3 January 1906 another says the prepared ham he sells is made by Taylor and is "the same to-day and forever", "quality not equalled by any other make", at sixteen cents a pound; on 5 March 1913 Phil Karg of 15 and 17 King Street offers "TAYLOR'S PORK ROLL, 25c lb.; pork goodies, 24c lb.; nice for boiling or slicing"; and on 4 January 1922 Wollner's of 23 Main Street prices "Pork Roll or Prepared Ham, 23c, By the Bag" as one item with two names. Mount Holly is deep in South Jersey, where the folklore says only pork roll is spoken — and it printed Taylor Ham in 1905. The tidy north-south line does not survive its own newspapers. Two things I could not verify and will not assert: the founding date of 1856, which appears in no court record or advertisement I could reach, and any standard of identity for the product. There is none. The entire Code of Federal Regulations names pork roll exactly once, in the ingredient table at 9 CFR 424.21, where a lactic starter or culture of Pediococcus cerevisiae is permitted "to develop flavor" in "dry sausage, pork roll, thuringer, lebanon bologna, cervelat, and salami", capped at 0.5 percent. Federally speaking it is a fermented, cured sausage that keeps company with cervelat.
Why this version works
The notches. A slice of pork roll is a disc of cured meat with a casing edge that shrinks faster than the middle. Left alone it pulls itself into a bowl, the centre lifts off the pan and only the rim browns. Four shallow cuts from the edge toward the centre let the rim shrink without dragging the middle with it, and the whole face stays down on the metal.
A dry pan and a hot one. The meat is already cured and already cooked through; nothing here needs cooking, only browning. It carries enough fat to grease its own pan within thirty seconds, and added oil only steams it. Medium-high, dry, and let it sit.
Cheese on the meat, not the bread. Laid on hot pork roll off the heat, the cheese melts into the ridges and seals the slices into one piece that lifts as a unit. Laid on the roll it slides, and the sandwich comes apart on the second bite.
The egg is fried in the pork roll fat. What renders out is salty, faintly sweet from the cure and slightly smoky, and it seasons the egg completely — no salt needed. Cooking the egg in a separate clean pan with butter throws that away and makes the sandwich blander for no gain.
