Dad's Best Brisket

My mother in law is a really good cook, so when she sends out a recipe I know its worth trying. She sent out this bbq brisket recipe several weeks ago and we finally tried it. It really was good and surprisingly easy. My husband is thrilled to know you don't have to have a grill to make good bbq brisket. 
Now, I'm not sure about your stores, but my walmart only had an 11lb brisket. It was like carrying a small child. I was kind of embarrassed to buy it but glad I did. We cut it in half and froze one half to have later. Yum. 

Not the best picture as we were in a hurry to eat it:) but there you go. I won't tell you how much we had (or didn't have) for leftovers.

Ingredients:
5-7 lbs beef brisket (mine was 5.5)
celery salt
garlic salt
onion salt (I used onion powder instead)
pepper
3 ounces liquid smoke (we used 4 oz; my MIL used mesquite flavor and I used hickory)
1/2 cup Worcestershire Sauce
salt and pepper
1 (18oz) bottle barbecue sauce (I typically use Walmart brand but with all the meat at stake I decided to follow the recipe and use KC Masterpiece)

Directions:
Center brisket on a large heavy piece of foil (we connected two pieces to make it long enough) in a roaster; sprinkle with liquid smoke. I actually used one of those disposable 9x13 pans you can buy really inexpensively at the store since I had one on hand.  My husband and I decided to put it fat side down. Sprinkle brisket with celery salt, garlic salt, onion salt, and pepper. There aren't exact measurements, make sure you don't skimp! Fold sides of foil over to seal and refrigerate overnight.

6 1/2 hours before serving open foil and season with salt, pepper, and Worcestershire sauce. We also cut off all the fat at this point, there was a lot. Reseal and cook, covered, at 300 degrees for 5 hours. Uncover and pour bbq sauce over brisket then cook an additional hour, uncovered. Let the meat sit for about 20 minutes before slicing. Although we didn't have to slice it, it fell apart. Enjoy!
