I worked in my garden most of the morning and had to work later in the day so I put the corned beef in the crockpot at around 11:00A.M. I normally do not like to use the crockpot too much because I think the meat tends to get overcooked. Corned beef as an exception. It tastes great even if it has been put into a crockpot for 10 hours. I put the carrots and the turnips in with it because the can take the longer cooking time too.
