cooking is in but I doubt it is a skill
That would be pretty neat though... Imagine a failed meal, and the PC says, "Eewh" and spits (and gains less from it). ~It would be neat for a few minutes anyway.
*I would not be surprised to find
anything done in http://www.youtube.com/watch?v=MiM3zn9qzis&feature=related, done in Skyrim; That includes cooking, mixing, and maybe even spell casting effects.
(except levitation, and questioning the king on his throne.)
