1 large red onion, sliced
1 cup orange marmalade
1/3 cup water
2 tablespoons rice vinegar
1 tablespoon soy sauce
2 teaspoons five spice powder
2 teaspoons grated fresh ginger
1/2 teaspoon hot sauce (what-have-you?)
2 cloves garlic, minced
1. Trim the fat as much as possible from the roast. Layer the onion slices in the bottom of your slow cooker. Place the trimmed beef roast on top of the onion.
2. In a medium bowl, whisk together the marmalade, water, vinegar, soy sauce, five spice, ginger, hot sauce and garlic. Pour the marinade over the beef.
3. Cover and cook on low-heat setting in a slow cooker for 8 to 10 hours.
4. Remove the beef from the sauce and slice. Serve over rice. Drizzle with sauce from the slow cooker.
