They make liquid smoke & you can fake a smoke ring. I actually did lots of briskets in the oven.YOU CAN ACTUALLY COOK A BRISKET IN THE OVEN ,YOU JUST DON'T GETTHE SMOKE FLAVOR!
12 ounce Coke
Bottle of Heinz Chili sauce
White onion diced fine
Fresh Garlic to taste
1 bunch of Cilantro chopped
Set oven at 350 mix all the ingredients together, Place brisket fat did down & pour the mix over top. Cover with lid or foil tightly. Cook 3-4 hours until tender. Remove all the pan liquids and put in a sauce pan to reduce. Put brisket back in over without a lid turning ever 15 minutes. Cook down the liquid in sauce pan until thick. Add your favorite bbq sauce to that and cover brisket with sauce with ever flip. Cook until 225 degrees. Let rest covered until serving.
My former idiot father in law thought it had a smoke ring from the sauce penetrating into the meat.
