What is the difference between roast and broast?

The main difference between a roaster and a crock pot is that the roaster has the capability of cooking foods at higher temperatures for shorter periods of time. You have the ability to set your own temperature, much as you would with a conventional oven. A crock-pot is designed for slow, low temperature cooking, over longer periods of time. Usually 4-8 hours. It's almost impossible to burn food in a slow cooker, ...as long as proper consideration is given (fluid levels, amount of food being cooked, time considerations, ...etc).
