"technically" speaking you have Nitrates/Nitrites involved, that's part of Cold Smoking:
quote:
Wood contains large amounts of nitrogen (N). During burning the nitrogen in the logs combines with oxygen (O) in the air to form nitrogen dioxide (NO2). Nitrogen dioxide is highly water-soluble. The pink ring is created when NO2 is absorbed into the moist meat surface and reacts to form nitrous acid.
The nitrous acid then diffuses inward creating a pink ring via the classic meat curing reaction of
sodium nitrite. The end result is a "smoke ring" that has the pink color of cured meat.
Real issue become spoilage and food safety.
Is there a reason you want to use the technique? The real issue would be food safety. If you are cold smoking it, the meat needs to get to 145 degrees for food safety.
So I'm trying to figure out the texture if it's "just" cold smoked.
How does he sell it? He may say he's cold smoking, but then finishes it at a higher temp to get the firm texture.
