There are other Runza recipes out there, but this is the one I grew up with.
Working with an enriched dough containing milk, shortening, and margarine requires patience. Knead the mass for a full five minutes until smooth and elastic to build adequate gluten structure. Allow the first rise to run a full 90 minutes in a warm zone until doubled in volume. Punch the dough down thoroughly before the final 30-minute rest.
Shredding a medium head of cabbage and wilting it in melted margarine demands proper drainage. Combine the wilted greens with browned hamburger and onions only after expelling excess liquid. Excess moisture will breach the four-by-six-inch rolled dough rectangles during baking.
Runzas freeze exceptionally well once fully baked and cooled. Store individual pockets in airtight bags for up to three months. Reheat frozen units directly in a 350-degree oven for twenty minutes to restore the crust without drying out the meat and cabbage center.
