I really don't understand dumping beef tallow over the top of the finished, wrapped briskets to add "juice". I can maybe see if it seals off the paper and wont allow as much moisture to escape? However, he did place 1st on the list so he knows his stuff for sure.
I totally get what your saying, BUT... not only did his place get #1 on the TMTF list, he also worked at three other TMTF places, and all of the other owners of Goldee's also worked at several different TMTF spots. That's how collectively they learned everything they needed at such a young age to run a hugely successful spot that earned them their own #1 spot on the list, and in less than 2 years of being open.
From comments he's made in a couple different videos he's pretty much saying ALL of the spots on that list do this, it's an industry wide trick, not something they came up with themselves. He learned it from the places he worked at before opening Goldee's. He did also say though that it's NOT a cure all and he can still tell if a brisket is dry, and "if your brisket is dry and you use a bunch of tallow, your not good at cooking brisket, your just good at dumping tallow over dry meat" lol
He also said this is mainly for aesthetics, because when a customer is at the cutting block and they grab a new brisket out of the warmer and open it up, the tallow gives the visual of a brisket that is super wet a juicy, and it just looks better to the customer than unwrapping a brisket with dry bark wrapped in dry paper. Almost like it's a psychological thing for the customers.
I do think it probably helps some due to the fact that those briskets have all been sitting in their paper wrap, in a warmer, for over 12 hours though.
What's funny is I've been using the overnight Sous Vide rest method for the last several months, and the briskets come out very similar to a tallow soaked paper wrap, because the vac seal pulls a little of the rendered fat out (just a little), and the briskest sits in it during the whole rest and when I pull them out of the vac seal they have that exact same tallow soaked appearance.
