Yes, I use the phosphate from Butcher BBQ in comps and at home. There is nothing better that I've found to tenderize rib eyes, or any other steak for that matter. I mix 16 oz. of beef broth with 1/4 cup of phosphate and marinade the steak on each side for 30 minutes. Be really careful because any longer than that and the steak can fall apart. I cook at a grate temp of 650* - 700* for about eight minutes. Two, turn, two, turn, you get the picture. The only thing that sucks is that for SCA your steak has to be cooked to medium, which I really find mentally hard to do!!
