I tried something new this weekend. Got a prime, top sirloin cap from Costco, and I was unfamiliar with this cut. It is also called a picanha, and evidently is a staple in Brazilian steakhouses. It also normally has a fat cap, although the two 2-1/2 lb. ones in the cryovac did not. So I rubbed and smoked them slowly until it was time to do a reverse sear. They both came out a perfect medium rare, and imo, I have to say that the taste and tenderness rivals the filet mignon for a fraction of the cost of a tenderloin. I will have to be on the lookout for more of these.
