Cold unsalted butter is the functional driver of this pastry, requiring careful physical integration to ensure flakiness without toughness. When you cut the fat into the unbleached all-purpose flour until it resembles coarse meal with pea-size lumps, those solid pockets of butter melt during baking at 400°F, releasing steam that separates the surrounding starch layers into distinct, delicate sheets. Distilled white vinegar in the liquid component acts as a structural deterrent against gluten development, preventing the dough from becoming chewy while you knead it gently on a lightly floured surface.
Dividing the workflow into distinct thermal phases prevents structural failure in the final pastry. Chill the wrapped dough rectangles for at least one hour to allow the gluten network to relax and the melted fat to resolidify before rolling. Simultaneously, spread the cooked ground beef chuck filling on a plate to cool entirely before assembly; wrapping hot filling inside raw pastry will melt the butter prematurely and create steam pockets that rupture the crimped edges. Rolling the disks on plastic wrap prevents sticking without requiring excess flour that would dry out the dough.
