Chocolate, orange and campfire, what could be better? Cook in individual aluminum sealed orange shells over campfire.
To clean the orange cut off the top of the orange, two fingers width below the top point. The end of the orange that has the biggest bump is the best side to cut off. Next, use your spoon to remove the fruit from the inside (kinda like cleaning out a pumpkin before carving). Be sure not to puncture the membrane of the oranges. Collect fruit and juice in bowl and use to make juice. Keep orange lids, as you will need these for cooking!
I used Trader Joe's brownie mix because all you have to add is yogurt. You can substitute for any brownie mix of your choice, but just remember that many other mixes require oil and eggs, which can be broken when traveling. Take the proper precautions to protect your eggs!
