There seems to be Cooking in Fallout 4 since for about half a second "Inspect Cooking Station" is highlighted when the protagonist is commanding the dog to pick up the wrench in the E3 video. It is the contraption that is to the right of the garage.
Neither of those were in Fallout 3 (the previous Bethesda Studio game).
