Have you ever thought about what it would take to make a peanut butter and jelly sandwich in space? There are a lot of kinks that the astronauts had to work out for even that simple cooking task.
First of all, they don't have regular bread up there. They use flour tortillas instead. Second of all, if they just let things go, they'll just float away... so that means there's a lot of velcro and tape involved in the preparation process. Third of all, be careful with that jelly! If a glob of that floats away and gets stuck to anything, cleaning it up might be quite a hassle.
