Does anyone else here follow the Pioneer Woman's blog? I've been wanting to try one of her brisket recipes for quite a while since it gets raves but I'm chicken and always make the one I know is good

This is the one I want to try:
Pioneer Womans Beef Brisket
Ingredients
2 cans Beef Consomme
½ cups Lemon Juice
2 cups Soy Sauce
5 cloves Chopped Garlic
2 Tablespoons Liquid Smoke (I would probably leave out 'cuz I think it's strong)
10 pounds Beef Brisket (other people posted they used as small as 3lbs and recipe still works)
Preparation Instructions
Combine first five ingredients in large roasting pan (a disposable is just fine). Place brisket in the marinade, fat side up. Cover tightly with foil. Marinate in refrigerator for 24-48 hours. When ready to cook, place pan covered in foil into a 300-degree oven. Cook brisket for approximately 40 minutes per pound.
When fork-tender, transfer whole brisket to a cutting board. Slice against the grain and place slices back into the cooking liquid. Serve immediately, spooning juice over the slices. Barbeque sauce may be used, if preferred.
You may store pan in fridge for up to two days or freeze for use at a later date. If fat collects and hardens at the top, remove and discard.
Brisket is great with mashed potatoes, with the juice spooned over the top. Its also great on a sandwich with melted cheese.
