Stopped by Aldi today to pick up a few things. They had packages of flat cut brisket, already corned, ready to cook. I started to buy one or two, but a quick read of the list of ingredients gave me pause. There were way too many things I couldn't pronounce. Including whatever it was that @rotuts mentioned that was the tenderizing agent (it started with a "p.").
I may change my mind and go back. Or not.
