Hmnmm, sharing my marinade for the Beef Ribs is something that if I tell you I might have to shoot you all for !!
Ok, ok ... I cheat !! I use a great product that I bring in from the USA called Head Country Marinade, it is simply wonderful on beef, be it ribs, steak, or brisket ... heck I even use it on burgers! I will try and remember to bring some with me to the comp in August so you can taste it.
Also, I cook the beef ribs on 250 F usually for between 6-10 hours until they are cooked, then glaze them with sauce, set at 275 and rest a bit before serving.
I always cook far too many, but there never seem to be any left!!
