Slow cook a brisket in any one of several gravies from onions and carrots to molasses/BBQ sauce. When it falls apart at the touch of a fork, you know it is done.
Goes well with mashed potatoes, green beans, (don’t use horseradish), potato latkes, Green Bean Casserole, spinach and even French Fries.
My mother cooked Jewish style pot roast like that. Brisket plus potatoes plus carrots plus onions plus a cooking gravy or sauce
