Sister brought a beef tenderloin butt, never heard of it. If you see one wrestle for it! I had to clean this one up, connective tissue and some sliver skin ... but not much. Broke down into three pieces. Simple prep, rubbed with Salt & Cracked black, add some butter, garlic and thyme. Cold smoked on pecan for 30 mins, then seared it, rested it. Add a baked tater with lots of butter and a simple salad, lettuce, tomato & pickled onions. Melt in your mouth tender!! I knew beef tenderloin was good, but whoever heard of a tenderloin butt.
