I keep running into interesting recipes that call for a slow cooker to be used but I never use a slow cooker. Can't a person cook that recipe in a normal way. Like boil and simmer in an hour or so? I suppose it depends on the recipe.
All slow cooking recipes can be done in a Dutch Oven....
start on stove top, finish in the oven.
I suggest you read this article from Serious Eats. About stovetops vs. pressure cookers vs. slow cookers.
