Calories are calories, and when it's cold out, fats are good becuase they burn the longest. I might not use Crisco under normal circumstances for anything but seasoning (great minds, et al), but I wouldn't turn my nose up at it for something where I need a fat/oil that can last for a couple years.
That being said, it is mostly air and doesn't add flavor. Might even take it away.
