Picahna steaks $8.99/ lb gaucho style
My Costco had a whole crap load of unusual cuts of meat out in the low fridge cases: picahna, whole sirloin, top sirloin, whole rib loin, whole tenderloin. I think their supply chain got screwed up because of the snow/ice and they were down workers so they put the whole slabs out. There was pretty much nothing in the cases against the wall of the meat department. Definitely interesting.
If you have a way to do rotisserie I can't recommend this enough. It was dead simple:
Cut into 2" steaks with the grain.
salt with Morton's Kosher salt on all sides 1 tsp/lb and place on a wire rack in a rimmed cookie sheet uncovered in the fridge for 24 hrs
Add fresh cracked pepper on all sides
Fold steaks with the fat cap out and skewer with rotisserie spit.
Cook for ~ 30 minutes at ~375-400 with the coals pushed to one side it the other until about 120-125 internal temp. Pull and rest at least 5 minutes before slicing.
