The regional table / Iowa
Iowa Chop
This is the one American regional dish whose origin is not folklore at all: a state agency named it, described it, and registered it, and a reporter wrote the whole thing down.
Most regional dishes come to a writer as a story somebody's grandmother told. This one comes as a news item. The Carroll Daily Times Herald of 22 April 1976 ran a piece by Paul Holley of the Iowa Daily Press Association, datelined Des Moines, under the headline "Iowa Chop Promoted by IDC". The Iowa Development Commission, it reports, "is hoping to make a pork cut — dubbed the Iowa Chop — as well known as its beef counterpart, the New York Strip". Doug Snyder, deputy director of the commission's agriculture division, "described the Iowa Chop as a fresh one-inch to one-and-a-half-inch center cut pork loin". Snyder said the title had originated with the Iowa Pork Producers' Association three years earlier, and that the commission was helping the producers promote the cut by registering the name with the Iowa secretary of state: registration "will give the commission control of the Iowa Chop name". His own gloss on what that control was for is the best line in the story — "The name may be used by any retailer or restaurateur who wants to promote the cut; we will only use control if someone tries to mislabel the chop." The commission expected to rely on word of mouth, Snyder said, "because regional names cannot be registered in wholesale meat suppliers' order books", and it was building an Iowa Chop display for the National Hotel, Motel and Restaurant Association convention in Chicago that May. A dish, in other words, with a campaign plan.
The federal record confirms his point about the order books by simply not containing the thing. 9 CFR 317.344 lists the major cuts of single-ingredient raw meat that a label must use, and the pork entries run: pork loin chop, pork loin country style ribs, pork loin top loin chop boneless, pork loin rib chop, pork spareribs, pork loin tenderloin, pork loin sirloin roast, pork shoulder blade steak, pork loin top roast boneless. There is no Iowa chop on that list and there never has been. Legally the thing in this recipe is a pork loin chop; "Iowa chop" is a promotional name for a thickness, and the 1976 story says so in the plainest terms. Two further notes on dates, because they are easy to get backwards. The campaign is a state one — the Iowa Development Commission and the state's own producers' association — and it predates the national pork checkoff by a decade: the Pork Promotion, Research, and Consumer Information Act is of 1985 and its order, 7 CFR part 1230, is what put a mandatory assessment on every hog sold and created the national board. And the name really does begin in the 1970s. The handful of earlier hits the Iowa archives offer are optical-character mirages: a 1936 crop report in which "Iowa corn crop" has collapsed into "Iowa chop" at 185,000,000 bushels, and a 1954 notice of the Iowa CHOP Committee, which was a relief charity shipping butter and cheese overseas. No printed recipe attaches to the 1976 announcement, so the quantities below were worked out for this page.
Why this version works
A short wet brine. Ninety minutes in salt water takes a modern lean loin chop from unforgiving to forgiving. Salt loosens the muscle proteins so they hold water through cooking, which buys you roughly ten degrees of margin on either side of where you meant to stop.
The thickness is the dish. At an inch and a half the centre is still climbing to temperature long after the surface has browned, which is the only way to get a hard crust on pork without drying the middle. Thin chops give you a choice between pale and overcooked; there is no third option.
Pulled at 140°F and rested. Carry-over takes a chop that thick another five degrees off the heat, which lands it at about 145°F — pink at the centre, firm, and still full of juice. The grey chop most of us were raised on is a chop taken fifteen degrees further, and that is the whole of pork's bad reputation.
Sear on the stove, finish in the oven. The crust wants fierce direct heat for four minutes; the middle wants gentle surrounding heat for fifteen. Trying to do both on the burner scorches the outside before the inside moves, and doing both in the oven leaves a grey chop with no colour on it at all.
