A slow cooker, also known as crock pot, cooks meat at 200 degrees on low and 400 degrees on high. It usually cooks meat in 8 to 10 hours on low and 4 to 5 hours on high. Slow cookers preserve moisture and make the meat tender. There are a lot of ways to use a slow cooker because you can put anything in it. Aisans like to mix ginger, scallion, soy sauce, sesame oil, etc with meat and sea food to make soup etc. I tried this with ox tail in a slow cooker.
