Step #2 Using a paring knife & your finger, stuff brisket all over with garlic.
Step #3 (I think this means to make slits in the meat & stuff small pieces of garlic into those slits & I would rub all over with garlic, to taste).
Step #4 Place brisket in a baking dish or casserole & bake this until browned on top, remove this from oven, turn brisket & return to oven until browned on both sides.
Step #5 Reduce oven temperature to 350 degrees F.
Step #6 Add enough beef stock to casserole to come up 1 inch on sides, cover with foil wrap & bake one hr.
Step #7 While brisket is cooking, stirring every once in awhile, until caramelized & most liquid has evaporated, heat a large skillet over medium high heat & saute onions in vegetable oil, about 20 mins.
Step #8 Set onions aside.
Step #9 Remove brisket from oven after one hr & add caramelized onions & all remaining ingredients, moving meat around to mix ingredients.
Step #10 Cover up & continue to bake this until very tender but not falling apart, another 2 to 3 hrs.
Step #11 Remove brisket to a carving board & slice.
Step #12 Strain reserved cooking liquids & pour over sliced brisket.
Step #13 Brisket may be returned to casserole dish & allowed to cool, then served the next day.
