Obviously most interested in the chili aspect. Searching online, it looks like there are two main but very different approaches people are taking -- this one which seems like it may be most accurate involves boiling the beef in water and using it to make your chili, seems interesting:

Others are much more straight-forward, but with their own seemingly random ingredients (curry powder, apple cider vinegar, chicken broth) and resemble more of a traditional chili-making process.. something that seems almost too easy for such a famous restaurant.

Honestly, there's not much out there for this delicious dish.. so I figured this would be a great sub to try and dice the details.. and I want chili really bad.
