A few years ago, I bought this from an Asian Market. It is a simple dry rub that you can mix with water and marinate, or, just apply dry directly to the meat. I have never marinated it, as it doesn't seem necessary, when you can do the dry rub method with great results. I have only used it on baby backs, and it is so succulent. I also only have grilled them outdoors, but the rub creates a deep pink, sweet/savory glaze, exactly like you would get with spare ribs in a Chinese restaurant. I haven't used it on oven ribs, but I would imagine it works great, so long as you finish it under the broiler to get that crispy finish. GREAT product!!
