Yes June you can make the best roast dinner in a clay cooker. First soak the clay pot and lid in water for 10 minutes. Then take a beef or pork roast and season with pepper, garlic, and onion and place it inside the pot. Peel and dice potatoes and carrots and put around the roast. Then take a package of onion gravy mix and add some water and pour over the contents. Place the lid on the cooker and put into a slow over - @ 160 and let it cook for 5-6 hours. It will be such a moist, tender, tasty roast dinner. Just add some rolls. You can also bake a chicken in it. Just put some lemon grass, pepper and garlic on the chicken and add a bit of water and let bake for 4-6 hours at 160.
Always have compliments on this meal - good luck. Once you use it, you will be hooked.
