This video addresses a very interesting point that I hadn’t thought of before. How do you cook an egg over a fire? Because the orange peel is moist, the egg won’t burn as easily and it will keep the egg moist. Bonus: The orange peel will imbue a little bit of orange flavor into the egg, giving it an interesting flavor. The underlying reason that this works is because the wrapper is thick and moist and as it cooks the moisture is released keeping the egg from drying up. Ostensibly, you could use anything that is naturally moist to reproduce this effect: onions, other citrus, banana peel, melon, etc.
