The beef is very tender. I used a 4pound rump roast and cooked it for about 12 hours. Added 2T. steak sauce to the gravy mixture as well as chopped garlic. The last 2 hours,I added red potatoes and carrots to make a complete meal! Also thickened the gravy with cornstarch. The whole family enjoyed it. Thank you for sharing the recipe!


Based on previous reviews, I ad-libbed a bit. I put in 2/3 cup of onions, twice the minced garlic, added several dashes of worchestershire sauce and two tablespoons of honey. The sauce was wonderful & I served it over white rice. Great recipe!


I was planning to make a different roast but didn't have all the ingredients. Fortunately, I stumbled across this delight. I made this exactly as written, with the exception of the cooking time. I cooked it on high for six hours. I will definitely make this recipe again, except next time I will add a few drops of Tabasco or perhaps a jalapeno-based sauce to wake the sauce up a bit. Don't get me wrong, there is nothing wrong with the sauce as is, and my husband liked it as is, but a smidgeon of some spice would make it pop just a little.
