This is a little bit of deliciousness my mom came up with yesterday...
Yes, that is Jello...and yes, it is in an orange peel.
I'm no sure what made her think to do this besides having a lot of oranges that she didn't want to go bad. She made fresh orange juice and then scooped out the half peel and used it as a cup to serve Jello. She used strawberry Jello (made with Mountain Dew instead of the cold water...which gives it a little extra zip).
You have to set the orange halves into a muffin tin first in order to pour the Jello in, then put the muffin tin in the fridge to set the Jello. When the Jello is set, pull the tray out and serve!
