Sous Vide and low and slow smoking also work to tenderize, though it’s not the easiest cut to do on the smoker.
Processing Sous Vide, on the other hand, is the clear winner for folks with that capability. 72hrs at 129-135 will produce a remarkably tender piece of brisket in the rare to medium rare range.
Pressure cooking and braising are also very effective at breaking down the connective tissue within the brisket.
Technically, the cow equivalents are flank and the short plate. Flank is very lean. Shrort plate is amazing. You get your skirt steaks and your hanger steaks from there. All of these are my favorites, huge flavor, need some care in preparation to be good.
A caution about jacquarding and food safety. When you jacquard, you take whatever is on the surface and you push it into the interior. Almost all the contaminants in modern meat are on the surface and are cooked off with searing. I don’t want to be a scold, 240, but be careful with that.
