Never tried marinating one that long! Here in KC we’re purists, not quite as much as Texas with just salt and pepper but close.If you really love brisket, have you ever "wet aged" one?
Stored in the bag @ 33 to38 degrees for 2-3 weeks, will
bring out the flavors!!! I'll also smoke a potato on my Treager
with a smoke tube for 4-6 hours (cold smoke) the wrap and cook!
You ever try the cap’o’ribeye steaks from Costco?When I do a brisket, Costco has PRIME grade in the bag. Try a 2 week 1st. and
the 1st. thing you will notice is a nice Corn finish and smell (not strong) when
opening the bag. I will do a quick rinse and pat dry. And as you said Salt and Pepper.
I'll also do a dry aged chunk of Rib-Eyes for 3 weeks and then cut steaks.
