Put Brisket in foil pan Fat side up. Pour 1 bottle of Lawrys teriyaki marinade on the brisket. Rub approx. 1/4 to 1/2 cup on brown sugar over the top of the brisket then sprinkle generously with fresh chopped garlic Shake pepper over it and cover with foil. Bake at 275 for 4 hours at least depending on the size of the brisket it may need longer. Once done trim the fat off the top and slice with an electric knife. Pour the remaining juice in to a saucepan and bring to a boil. Mix corn starch and water and pour into juice to thicken, then pour over the sliced brisket in the pan. This part is kind of messy but it's worth it! Enjoy!
