Jello

"Hey, what happened to the, um, to the blue jello? My favorite – all of a sudden it's off the menu."

- Rodney Mckay

Jello is a gelatinous desert found on Earth that is made from a mixture of gelatin, sugar, and fruit flavoring, dissolved in hot water and chilled until firm. It is served in both the mess halls of Atlantis and the SGC. Rodney Mckay is known to eat jello, liking blue the most, as well as Samantha Carter.
