The regional table / Nebraska
Runza
Everything that goes wrong with this dish goes wrong for one reason, which is water, and the fix happens twenty minutes before the dough ever sees the filling.
Two things about this food sit at different ends of the record, and it is worth being straight about both. The word is a registered trade mark of a Nebraska restaurant company as well as the ordinary name people here use for a thing they bake at home; this page makes the food, not any company's product, and no company's recipe is published or reproduced below. And the word itself is young in print. Nebraska runs its own open archive of its digitised newspapers at nebnewspapers.unl.edu, and searching the whole of it turns up no occurrence of the word before 9 July 1963, when The Daily Nebraskan carried a small advertisement for a Runza Drive-In selling "A COMPLETE MEAL in SANDWICH". Every earlier hit the search offers is an optical-character mirage: papers from 1915 through 1919 break the name of the Mexican president across a line as "Car-" and "runza", and one 1919 letter-writer splits Sancho Panza the same way. The cousin name does no better. "Bierock", which the same people carried into Kansas, returns nothing at all in the entire Nebraska corpus — not one page, in any year.
The people, by contrast, are documented to the decimal point, and they are the reason the dish exists. Hattie Plum Williams, working at the University of Nebraska, published A Social Study of the Russian German in the university's studies series in 1916. She was writing about Lincoln, "a city of some 48,000 inhabitants, of whom one seventh are Russian Germans" — about 6,500 people, "the largest group of these people to be found in any one city in the United States", and in 1914 one third of all the births in the city were of Russian German parentage. They came from the Volga provinces of Saratow and Samara; their ancestors had gone to Russia from the German states in response, as Williams puts it, "to the manifesto of Katherine the Great in 1763", and emigration to America "began in the seventies" once the reforms following the freeing of the serfs took away the self-government, the schools and the exemption from military service they had been promised. Lincoln was the distributing centre for the whole state, and many families were "ticketed direct from Saratow to Lincoln via New York, knowing nothing of any other places in America than these two". Williams also notes, in a chapter about infant health, that the mothers kept their houses cool in summer "because she has been accustomed to cooking outside" in a summer kitchen. A filled bread baked in quantity, eaten in the hand, good cold, is what that kitchen produces. No document anywhere in that record prints quantities, so the ones below were worked out for this page.
Why this version works
Sealed seam down. The weight of the filling holds the seam shut while the dough sets, and the twenty minutes of bench rest after shaping lets the gluten relax so the seal does not pull open in the oven. Seam up is how most split runzas were made.
An enriched dough, not a bread dough. Milk, egg, butter and a quarter cup of sugar give a soft close crumb that stretches around a heavy filling without tearing and stays tender the next day. A lean water-and-flour dough bakes into a crust that shatters at the fold and goes stale by evening.
Onion and pepper carry it, not spice. There is nothing in this filling but beef, cabbage, onion, salt and a lot of black pepper, and that is the point: the sweetness of the bread against the pepper is the whole flavour. Anything you add — garlic, paprika, cheese — moves it somewhere else, and the somewhere else is usually worse.
The filling is cooked dry before it goes in. A pound of cabbage is mostly water and it all comes out. Cook it out in the pan, uncovered, until the bottom of the skillet stays clear for a second after you drag a spoon through it, and the dough seals onto a solid. Put wet filling into raw dough and the steam has nowhere to go but into the crumb, which is how you get a pale, soggy base and a seam that bursts.
