We had slow cooked short ribs , mashed potatoes and Brussel sprouts. It wasn’t a big piece of beef and I first rubbed it with a sauce which I concocted myself and wrapped it in foil to sort of marinate for a couple of hours. Placed in oven 160’C for 3 hours, then opened foil , splashed on more sauce and cooked for another hour. It was fall off the bone tender.
