I will have to watch this - can you share a link?
While at a BBQ competition a few weeks back, I walked away with some leftover meat that had been given the full competition treatment with injections and I noticed that by day 2 or 3, the leftover pork butt that had been injected started to taste like ham and the brisket started to taste like beef jerky as a result of all the seasoning/nitrates in there that were curing them. Really put me off injections for home use as I am typically eating BBQ for 3-5 days afterwards.
