FAQ
Can I use a different cut of beef for this recipe?
Yes, chuck roast works well but may need additional 30-45 minutes cooking time. Bottom round or rump roast are also good alternatives with similar cooking times.
What if I don't have a cooking bag?
Cover tightly with heavy-duty foil instead, creating a sealed packet. Cooking time may increase by 15-30 minutes to ensure tenderness.
How long will leftovers keep in the refrigerator?
Properly stored leftovers will keep for 3-4 days in the refrigerator. The meat actually improves in flavor as it sits in the sauce.
