Comfort.
What is comfort to our eyes? The feeling of home? A completely relaxed body? Or conversely a hyperactive session of our favorite sport? A visit to a museum can be comforting to many, but just because we stand still for hours in front of a magnificent piece of art it doesn't mean that our mind isn't going 100 miles an hour.
Generally we tend to associate the word comfort with something soft, fluffy, enveloping and translating this abstract and deep feeling into food is quite an interesting endeavor.
Certain ingredients can, by themselves, elicit such an emotional response so much so that we may find ourselves savoring luscious sour cream by the spoonful directly from the tub in these deep moments of need. The texture of fatty rich food makes us melt into expressions of pure enjoyment, probably an instinctual response to the fact that we are well provided for the cold season.
