Yes, I do, a nice quick and easy way to make a meal. Dont use it often but sometimes. As for tips I would get a slowcooker book and try some recipes. Follow directions and you will have a delicious meal
A chopped onion, chopped clove of garlic, cover the butt with Tony Cacherie's seasoning, and cook on low for 6 hours or thereabouts. Then shred the meat with forks and put barbecue sauce to taste on it.
I have always had a dislike for seafood until we moved (I really don't want to share where we live now for privacy purposes though) and now we have fresh crab and OH MY!!! So good. So expensive too!
