Sweet and Spicy Brisket

I made this last night and it was great! Then, today I made the same thing with chicken but I cooked it in the crock pot.

3 lb brisket
1/2 can beer
Meat tenderizer
2 tbsp minced garlic
1/2 cup brown sugar
1 tablespoon of each of the following: onion powder, garlic powder, ground mustard, celery salt
1/2 tablespoon of each of the following: cayenne pepper (more or less to taste), cumin, paprika, sage

Generously sprinkle meat with tenderizer. Cut small slits in meat and stuff with minced garlic. Mix together all seasonings and sugar. Rub into meat very well. Put brisket in baking dish and pour beer over it. Cover tightly with foil or lid. Bake at 350 for 2 hours. Then, reduce heat to 200 and cook for 7-9 more hours, or until fully cooked and tender.
