I made this delicious slow-cooker corned beef and cabbage dish today, using this recipe with a little tweaking. I added some stalks of celery and button mushrooms to increase the veggie content and added a sliced apple to the mix to compliment the apple cider vinegar.
I set the slow cooker on low, instead of on high. It was more than done after 9 hours. I would be hesitant to cook the dish on high heat in the slow cooker using my cooker.
