If you live in Miami you have heard of Picanha (pronounced "pee-KAHN-ya") its the most popular cut of beef in Brazil and it can be found in many popular brazilian rodizios and steakhouses such as Fogo de Chao and Texas de Brazil...
While Picanha is popular in Brazil, it is also widely known accross Latin America. Venezuelans call it "Punta Trasera" and Argentinians and Uruguayans refer to it as "Tapa de Cuadril". However, in the US it is unlikely to be found at your local grocery store or butcher.
Picanha is famous for its amazing price value proposition, many will take a Picanha with all its tenderness and flavor over much more "premium" cuts such as the RibEye, the NY Strip and the Porterhouse.
The texture and flavor is similar to that of your sirloin, except much more intense thanks to the rendering of fat during the cooking processes... and the cooking process is extremely simple
Yes Picanha is THAT good... and ours is particularly amazing made of USDA Prime and USDA Choice beef (and yes, quality does make a difference)
If you walk up to your butcher and request a Picanha they will most likely offer you a "tri-tip"...
The thing is, Tri-tip is NOT Picanha. The only similar thing about the tri-tip and the Picanha is that both of them come from the SIRLOIN of the cow... and whatever your publix butcher says, NO, Picanha is NOT just "untrimmed trip-tip", it is completely different.
