Mighty Muscles buff skill

[Trismegistus]

So I packed my backpack so tightly that I now can't perform my normal reach around to empty it. I don't want to glutton. I have a flask full of marvelous yolk but can't empty it into my yolk-loving mouth. What kind of skill do I need to complete this task?

EDIT: I found an answer to my problem, however it is not the answer to the question. I no longer care though as I believe it to be as I already assumed. There is no skill for drinking. I only had 0.05 yolk in my flask. The only option was to empty it. I assumed maybe I needed the Hideworking skill since that allowed the creation of the flask, however that didn't work. I then assumed maybe it was tied to some egg recipes so I unlocked Simple Cooking. Nothing. The problem turned out to be that testing to see if I could drink 1L by trying to drink 0.05L was an invalid test. It is apparently impossible to drink 0.05L of egg yolk.

you drink in multiples of 0.1L, needing ten gulps, so 1L total, to get a full buff.
