I have two racks and a barrel smoker. I’ll test the skin on/off theories.
My words were in response to a reasonable Twitter-based give-and-take between Andrew Zimmern and some food writers, who were discussing whether to cook pork spareribs with the silverskin on or off. (See the discussion after the jump.) Before I knew it, I had turned my vacation day into some quasi-experiment that forced my dinner guests to become unwitting guinea pigs. Happy Memorial Day, everyone!
Truth be told, my experiment started promisingly enough. It was only when I turned to the aluminum foil — which I had adopted recently to prevent oversmoking the ribs — that the whole affair took a dark turn. Literally. (More on that later.)
Now, I understand the impulse to want to skip the silverskin removal. The degree of difficulty is high. The membrane’s slippery texture and structural vulnerability — it tears easily — can make the process as frustrating as removing lint from a Velrco surface. Many people, like Zimmern and writer Michael Ruhlman, prefer to let the silverskin suffer the shriveling indignities of the low-and-slow cooking process.
Others, however, think my position is pure ego-driven fantasy, perpetuated in order to establish the supremacy of my silverskin removal skills. I will not discount this opinion. Sometimes habits become ingrained even though the reasoning behind them are only marginally sound. I’m thinking specifically about the myth of slowly incorporating heated broth to make the perfect risotto.
With the two racks trimmed, seasoned and ready to roll, I threw them in the smoker fueled with a combination of cherry and apple woods. The temperature fluctuated between 200 and 225 degrees, depending on how absorbed I became in the Nats game on TV. The smoke levels were generous, but not gas-mask inducing.
Smoking issues aside, the racks emerged from the smoker with one wildly unpredictable result: The ribs with the silverskin still attached were more fall-off-the-bone tender; the meat barely clung to the ribs, as though they had been smoked an hour or two longer than the other rack. The only plausible theory at our table was that the silverskin held the heat and moisture better, essentially breaking down the protein faster than the skin-off rack.
The silverskin-removed ribs, by contrast, held their shape; the meat on the bone still had chew and pull, which is how I prefer my ribs. (For those who might suggest that one rack was closer to the heat source, I should note that I carefully rotated the racks to promote even smoking for both.)
With that said, I would be remiss if I didn’t point out that the tasters at our table felt that both racks were, essentially, equal in flavor, save for an extra blast of salt and pepper here and there (which I chalk up to uneven application of the seasoning). No one seemed to care about the ribbon of silverskin glued to the back of some ribs; it did not interfere with their enjoyment.
Bottom line: I have to give the nod to Zimmern and Ruhlman. The results of this one simple test lend credibility to their argument for leaving the silverskin undisturbed. Even if you prefer your ribs with more chew, you could simply reduce the cooking time.
I humbly take my hat off to you gentlemen.
