Guys & gals, I need food stuff help. 
This feels like something I should be able to clearly nail but who knows..
I need a meal/recipe/drink to round out my **Celestial** themed food item for the 52 week cooking challenge!!
I have sugar cookies I plan to decorate but WTH is celestial/galactic/cosmic to go on them? 
I still plan to do a Hitchhikers Guide to the Galaxy 'Pan Galactic Gargle Blaster' cocktail because that's my shit.. & no one else touched that idea.
