So I stumbled across a recipe over the weekend that I've never seen before using the Picanha cut of beef. It involves trimming the fat cap down, cutting a pocket and turning it inside out and stuffing with ingredients. The video below shows the process. I couldn't find one in English but you'll get the idea. I've seen some stuffed with blue cheese, bacon, mozzarella etc. I'm sure it's up to your imagination. I've also seen some sear the outside before turning inside out to get that char flavor on the inside. Looking forward to trying this on the PBC...
