That'sa heckuva slab !!!!
When I do luck out & get a big rack 'o' beef, I try to find a big piece of charcoal to cook it with.....Exmp.:
That's a 3-bone short plate............
But seriously, you did the hard part, there's that 1st membrane & there's a second one that's not worth the trouble.....or you may have already gotten that one, your's look pretty well cleared.....
I go mostly straightforward like Eastex is saying, or if the stuff Chris is talking about is available, check that out...
Other ideas: I make little shallow cuts, just nicks, all over the fatcap side & it seems to get the rendering going a little better.................
These ones also got the unsweetened cocoa powder after S&P& a little garlic powder.....
Oh & one last thing I remember from having gooned out before.....don't rush it on beef ribs, do them when there's time toallow for getting them tender.....you can foil with broth near the end,
B. ribs is one time I don't mind doing that......
