Just about every time I watch a sci-fi show or movie about space, there always seems to be "regular" food on board. That is, stuff that we on earth (and more specifically Americans) recognize as "home cooking", things with potatoes, beef and chicken, soups, and a wide variety of other things.
As far as I know, most of the food the astronauts use today (please correct me on this) is dehydrated or altered in such a way to make it feasible to bring into space (like a backpacking meal).
I'm curious of what technological costs would go into a spacecraft being able to carry a kitchen capable of cooking raw foods, specifically for the spacecraft and not for transport to colonies or other such things. I think, obviously, one day we may have such technologies, but I'm more curious about the next 100 years or so. Will we be able to accomplish this, or are the next few generations of astronauts doomed to eat "space food"?
