Ok almost nothing I do has precise measurements so you will have to take some of the spices with a literal grain of salt.
You start off basically making corned beef. I took a 5 pound brisket and submerged it in 3 quarts of water. To get there I heated up brine that considered or the water, one cup of kosher salt and a 1/4 cup of the pink curing salt. I added a decent amount of sugar and let it dissolve. Then probably 3 tablespoons of coriander seeds and pickling spices -- they're actually just called pickling spices. I put ground mustard, onion powder, fresh garlic and a few shakes of Lawry's seasoning salt in it. Let all that come to boil, then cool it down, then dunk the meat in it. I let mine sit in the fridge for 5 days.
Sometimes when I make my bacon I feel like it's a little too salty afterwards. So this time knowing there was a lot of salt in the brine, I took the meat out, rinsed out the container and then dunked it in some water for 40 minutes. I don't know if this worked or what, but I can tell you the meat wasn't overly salted at all, so I will keep doing it.
Dried it all off, then made the rub. I always put a tablespoon of pepper for every pound of brisket, so 5 tbls here. I then put 3 tablespoons of ground coriander, 2 tbls of paprika, then hearty shakes of onion powder, garlic powder and one shake of ground mustard. I didn't add any salt since it's already in the meat. I let the rub set on it for 2 nights.
I then smoked it (6 hours) sliced it and there you go. I was going to let it rest and then steam it, but we were hungry so I just sliced it. We'll try that next time.
It's a lot of work but worth it!
