The way I see it... Corned beef is a fancy way to sell you a lousy cut of meat. Brisket is a tough chewy cut. It does need to be cross cut with a sharp knife and that appears above in Neil's post.
If you have the time and space in a refrigerated compartment, you can treat yourself to something better. I use the refrigerator in my motor home, when the motor home is parked at home.
Make good corned beef
I boil 6-8 quarts of water
1/4/ to 1/2 cup salt
1/4 to 1/2 cup sugar if you like
2 to 3 ounces of the above pickling spice
4 to 6 pounds of "Spencer Roast" (Next to the shoulder roast(
(You may have to special order from your favorite butcher)
Cut the roasts into 2 to 3 pound pieces.
After the water cools add the meat and refrigerate for 6 to 10 days turning the meat every couple days.
Remove the meat from the brine and add to a crockpot for about 5 to 6 hours. Add cabbage or other vegetables (not potatoes though) at the last 2 to 3 hours. I feel potatoes steal the flavor from the meat.
You may also directly freeze the home corned Spencer roasts for enjoyment at a later date.
There is no food dye in your home made corned beef and you are using a nice cut of meat with plenty of marbling.
You should be able to cut the meat with your fork.
