I have a beef brisket which has been in the freezer, and is like a rock. Do I have to defrost it completely before I cook it? Can I just put the frozen slab into the dutch oven and let it defrost and cook at the same time? What is the advantage,if any, of defrosting?
I plan to cook it in beer, onions, and homemade chili sauce (basically tomato sauce, brown sugar and vinegar) if that makes a difference.
