In Star Wars: The Force Awakens, Rey received food portions and heads back home, where she adds liquid, and it instantly rises to bread. That was entirely real, not CGI, and now you can learn how to make Rey's portion bread thanks to Starwars.com.
You can make it in under a minute just by pouring ingredients into a cup, add liquid and heat, and the site shared the recipe for it:
