I've been wanting to try this myself. The problem is I am the only one that will eat CB in my house.
Oddly enough my wife won't eat corned beef when I make it from the package. But I made home made corned beef and she ate it and liked it. Go figure.
This is the recipe I used although I was missing about half the spices. And I subbed other stuff. Like home made mustard instead of the mustard seed.

5# brisket in the fridge for 10 days was tough to work around lol. Plus I had to time it so cook day was Saturday...10 hours in the crock pot, 4 on high and 6 on low. But man it was good!
