Not when I have this (an enameled cast iron French Iron from Le Creuset):
and it makes meat come out looking like this:
The flavor difference between this and what comes out of a crock pot is amazing. I used my crock pot recipe for Cafe Rio Pork and didn't change a thing. Wow, now you can really taste the flavor. It came out tasting like it was prepared in a smoker. I am so excited to try more recipes in my new pot!
