Goetta
The oat is the whole argument. Take it out and put corn meal in and you have scrapple, which is a Pennsylvania dish; leave it in and you have the breakfast of a German pork town.
Cincinnati was a hog city before it was anything else, and the numbers are in a book you can open. Charles Cist's Sketches and Statistics of Cincinnati in 1851 gives the trade a chapter of its own, headed The Hog and its Products. Pork, he writes, is our great staple, and hogs to the number of four hundred and ninety-eight thousand one hundred and sixty have been cut up in the market in a single year. The season ran from November to March. There were ten slaughter houses on the edge of town, fifty feet by a hundred and thirty, boarded with movable lattice that was kept open for the air; the blood ran into tanks and was sold to the makers of prussian blue; and at the end of the line a man called the gutter worked, Cist says, at the rate of three hogs to the minute. The same book counts the city's foreigners by birthplace and puts Germany at the head of the list with 30,628, far ahead of Ireland's 13,616. A German city and a pig city in the same square mile is the whole explanation of goetta, and neither half of it has to be guessed at.
The grain is documented too, if from an odd angle. USDA Farmers' Bulletin 420, Oats: Distribution and Uses, by C. W. Warburton of the Bureau of Plant Industry, issued in November 1910, notes that most of the oatmeal then manufactured was more properly termed rolled oats, though the cracked or cut grain, commonly known as groats, was still used to a limited extent — and that long cooking not only makes it more palatable but greatly increases its digestibility. That cut grain, sold now as steel-cut or pinhead oats, is what goetta is built on, and the bulletin is telling you in 1910 both that it had already become the minority product and exactly how to treat it. The German word for it is Grütze, which an 1882 German-English dictionary glosses as groats, grit, and traces to an old verb meaning to grind. What is not documented anywhere I could reach is the word goetta itself. It is in none of the Ohio cookbooks that are old enough to be public domain — not in Buckeye Cookery of 1877, not in the Christ Hospital Cook Book printed in Cincinnati in 1914 by the hospital's own dietitian — and an exact-phrase search of Ohio Memory, the Ohio History Connection and State Library of Ohio programme with a million pages of newspaper text behind it, returns thirty-three pages, the earliest dated 12 October 1961, in a Warren County weekly whose run there begins in 1807. Ohio Memory does not carry the Cincinnati dailies and loc.gov refuses scripts, so that is a hole in the record rather than proof of anything. What the old Ohio book does carry is the rival: Buckeye Cookery prints a scrapple made from a boiled pig's head, chopped fine, returned to its skimmed liquor and thickened with corn meal till of the consistency of soft mush, then poured into pans, set in a cool place and sliced and fried for breakfast in winter. That is goetta's architecture exactly, with the wrong grain in it.
Why this version works
Overnight in the pan. Warm goetta cannot be sliced and will not crust; it spreads and steams. A night in the fridge sets the gelatin and lets the whole loaf dry slightly at the surface, and a dry surface is the only kind that browns.
Pinhead oats, not rolled. Steel-cut oats are the whole groat chopped into two or three pieces, so the starch is locked inside a grain that holds its shape for hours. That is what gives set goetta a sliceable body with texture still in it. Rolled oats are steamed and flattened, dump their starch in twenty minutes and set into a smooth paste that collapses in the pan.
Three hours on the lowest heat. This is Warburton's point from 1910 about long cooking, and it is also the difference between goetta and porridge with meat in it. The grains have to give up enough starch to bind the meat but keep enough structure to stop the slice turning to mush over the heat.
The oats cook in the pork broth. Every bit of gelatin and rendered fat from the shoulder goes into the grain rather than down the drain. The gelatin is what makes a cold loaf firm enough to cut half an inch thick and carry to a hot skillet without breaking, and the fat is what lets the cut face brown.
