Why This Recipe Works

This recipe works by leveraging slow cooking to convert a tough, lean cut into tender, flavorful meat. The extended cooking time breaks down collagen into gelatin, creating a moist texture while enriching the sauce. The Dr Pepper contributes sugar and acidity, which help tenderize the meat and create a balanced sweet-savory profile when reduced. Cornstarch thickening ensures a smooth, cohesive gravy that clings to the meat. At approximately 350–420 calories per serving, this dish offers a satisfying yet moderate-calorie main course.
