Hi. I am new to forums, so I apologize if I appear to be a total ditz. I bought a pork shoulder roast and found a delicious sounding recipe for a stew. The recipe instructs me to use a slow cooker. Don't have one. It says to cook on high for 1 hr then on low for 1 hr. Can I just slow cook it on top of the stove in a dutch oven? If so, how long should I cook it and how high should the heat be? Thanks
