Remember Mark Watney in The Martian modifying the astronaut habitat to grow potatoes? Over at Quirk Books Danielle Mohlman has posted some potato recipes from various online sources. And if you're interested in food real-life astronauts would eat, Tara Ziegmont of Feels Like Home has instructions for making astronaut pudding. The post includes a video of an astronaut on the International Space Station demonstrating how he and his co-workers make dinner. Yum.
