I think he is nuts. I just looked up his standing in the KCBS rib category and found that he is in 138th place in competition ribs.
Another thing, his recipe which is different on several websites is NOT a brine but is a marinade.
Google Jack's Old South rib recipe and check his recipe for ribs and see that he tells it different on each article or website.
I think I will stick with my no-brine ribs.
