I've got a large chunk of Elk bottom round roast I want to cook in the crock pot. Usually my wife will make a regular type roast in there but she is working 3 12 hour shifts at the hospital this weekend so I can't ask her for tips on cooking this. What do I need to put in the crock pot with this piece of meat? I can use a grill pretty good but other than dropping in this meat and turning it on, I don't know what I am doing. What do I need to get from the store?
