3-4 lb. trimmed brisket
1/8 oz. Adolph unseasoned meat tenderizer
1/8 oz. garlic salt
1/8 oz. celery salt
1/8 oz. onion salt
1/2 oz. liquid smoke
1 1/2 oz. Worcestershire sauce
1/2 oz. Italian dressing
1/2 oz. catsup
2 tsp. prepared mustard

Put the brisket in a glass dish. Put all of the above ingredients on the brisket. Cover with foil and marinate for 3 to 4 hours in the refrigerator. It's better if you marinate overnight.

The next day bake covered in a 350 degree oven until tender, approximately 3 1/2 to 4 hours. Baste occasionally. Remove foil cover during last 30 minutes so meat can brown.
