I have a process that calls for a 6-8 hour slow cooker braising of inside skirt steak. The skirt steak becomes incredibly soft and the connective tissue adds a lovely gelatinous luxurious mouthfeel when large chunks of the skirt steak are served from it.
I want to replicate this in half the time. I tried with cooking approximately 15lbs of peeled inside skirt steak for 4 hours in a covered hotel pan with some water in the pan but while the steak was delicious it was not "fall off the bone" soft.
What are commercial ways of cooking large volumes of skirt steak quickly retaining maximum texture and flavor?
