Hi All - I picked up the seasoned brisket flat shown in the attached picture from Sam's Club and it was really good. I smoked following the directions on the package (250 degrees in smoker for 2 hours, wrap in foil, and cook until 201 degrees, which probably took 3 or 4 hours wrapped if I had to guess) except I didn't bother with using a small container of water in the smoker. I used hickory wood. It had a nice level of spiciness (probably a little bit too salty though) and I want to try to replicate the seasoning recipe. It was a wet paste rather than a dry rub.
Here were the ingredients: Seasoning [Sea salt, spices, dehydrated garlic, ground coffee, dehydrated onion, sugar, dried chipotle pepper, dried ancho chile pepper, dried guajillo chile pepper, natural flavors, soybean oil (processing aid), mushroom powder]; canola oil, vinegar powder (to preserve quality), rosemary extract.
Does that sound like any sort of seasoning that you have previously tried and come across anywhere?
