Rump Roast in your Crockpot

The name rump roast just makes me laugh. When I started cooking, it actually intimidated me until I learned how to defeat the rump in the kitchen. In the UK, they call the rump roast a Silverside and I like that a lot better. So here are a couple of facts about the rump roast:

It comes from the bottom round, the rear leg of a cow
It’s a tough piece of meat and tastes best when roasted slowly until tender
The three best ways to cook rump roast: A crockpot, braised, or marinated

Why the name Silverside? The UK isn’t the only industry to call the rump roast by a different name. The beef and pork industry changed 350 names of cuts of meat to be more appealing and sell more.

Just in case you run to the store to buy a rump roast, it will probably be labeled something such as Leg Sirloin now. You can actually use any tough cut of beef interchangeably with this recipe and get great results. Why not check out the Sonoran Spice Range of spices?

Crockpot / Slow Cooker

Everyone always asks what my favorite crockpot is. I have used at least 5 different brands of slow cookers and crockpots and have finally landed on my favorite. I now own 4 of the same one and they never fail me.

My favorite all around crockpot is the Hamilton Beach Set ‘n’ forget Slow Cooker (6 quart).
