last week that was marked "Plate Skirt Steak" and I thought it was a skirt. I marinated it as usual for fajitas and it was so tough that we couldn't even eat it. What did I get? I just did a search and found this link (skirt is at the bottom) and it says that plate is skirt but it also says it should be pounded thin. I have never done that to skirt before. Is that why it was so tough? I cut the large piece of meat into portions and froze them so I really need to know what to do with it. TIAhttp://www.foodsubs.com/MeatBeefB&F.html
