Trim off any loose fat from the ribs, then coat in the rub and leave for 24hrs. Next day, pre-heat the oven and switch on the smoker, when the oven is hot, place the ribs on the Vision bake and "seal" for 20 mins. Smoking during this time will give the beef great flavor. After 20 mins, take out the beef and place into a deep gn container, add the cooking liquor (below), cover tightly and place back into the oven. Fry off the onions and garlic, once soft, add the beer and reduce by half. Then, add the chicken stock, black treacle and thyme. Use this to cover the ribs. Next day, strain off the cooking liquor, boil and whisk in the tomato sauce, brown sauce and yellow mustard. Thicken if needed. Use this for the ribs. Serve the ribs with mashed potato and coleslaw.
