This brisket is so tender and moist . My family loves this brisket when I make a gravy and homemade mashed potatoes...There is always enough left over to make philly sandwiches with slow cooked onions and peppers
Spray large deep pan with cooking spray , making sure pan can be covered TIGHTLY with foil NOT touching meat. Fat side up.
Pierce meat ( I use a ice pick ) really good . Pour entire bottle of allegro marinade on and under meat. Cover meat with almost whole bottle of montreal steak seasoning ( I use about 3/4 of a 3.4oz. bottle. Sprinkle garlic on top of brisket, now cover top ( fat side up ) with about 1/4 bottle of 6 oz. rib tickler.
Cover tightly with heavy duty foil and cook for 12 hours at 225 . The key is not to open and let your steam out . Make sure foil does not touch meat and the foil stays tightly on your pan.
