How do you make gray corned beef?

After you Brown your Beef then transfer it into either a large stock pot or a slow cooker then cook over Low heat for about 8 to 10hrs with your Potatoes and Carrots add any other tender vegetables( Cabbage, Corn,Green Beans NOT Canned Green Beans about 1-2hrs before serving. If you are going to use canned Green Beans i do suggest you rinse them first before adding them to the pot,Doing so will get some of the bitterness out that can take over your soup taste. Hope this Helps
