After marinating a piece of beef rib-eye the night before in a Sopasco rub, which is a mixture of spices (paprika, cumin, coriander, oregano, but also brown sugar, salt, pepper, garlic, etc.) to give it flavour, I got up around 5:30 a.m. the next day to start this slow cooking process known as 3-2-1 cooking. For 3 hours, the meat is smoked/cooked at around 100°, then continued for 2 hours at the same temperature, wrapped in aluminum foil and topped up with the liquid of your choice. I used apple juice and cider, but you can also use beer. It helps the meat melt. Finally, during the last hour, the meat is removed from the foil and brushed with barbecue sauce, before being put back into the oven for lacquering.
