Pork roast
Provides the meat that becomes tender during long, moist slow cooking.
Potatoes
Absorb cooking juices and add starchy body to the dish.
Onions
Add sweetness and savory depth as they soften in the cooking liquid.
Ketchup
Adds tomato sweetness and acidity that shape the sweet and sour sauce.
Vinegar
Provides the sour note that balances the sugar in the sauce.
Brown sugar
