I found this, and it seems that Dante has taken this and reworded it with "pinch", a cooking measurement. All I can think of is basically Ramsay always demanding more from food or something? Possibly taking advantage of Julia's calmness as well, as she is generous to him and he'll just demand more and more from her and the waiters.

That's my theory.
