I purchased the Crock Pot brand, as I was unhappy with another name brand cooker.
The 7 quart crock pot is a very generous size, perfect for a chuck roast.
I put celery, quartered carrots, quartered potatoes, and onion in the crock pot.
I then braised both sides of the chuck roast in a fry pan, then I added the roast
to the crock pot, followed by 1 can of beef broth. The recipe instructed 10 hours on low, no peaking,
when the roast is tender, set the crock pot on the warm setting, until supper time. The roast was
very tender after 10 hours on low, the warm setting kept everything warm until serving.
Crock Pot Brand is the only brand for me.
