The first thing you will need to do is to hollow out the egg.
You will need
eggs -either plain or already dyed. I've only done this project with commercial
chicken eggs, but go ahead and experiment with any type you’d like.
A pointed object - I prefer to use a tack, but feel free to use a straight pin,
pen, or even an ice pick if you feel more comfortable with them.
A bowl/ sink- this is to empty out the insides in. Use a bowl to set aside
the amount of egg you will need with your cake recipe to limit the
waste that comes from this project. Also, the bigger the bowl you
use the less misses you'll have when empting the egg.
News paper- Optional. If you don’t want to make a huge mess in your kitchen,
it's best that you put down a few sheets of news paper or the like to prevent
future frustration as you scrape away at the egg bits that missed the target.
Time - this project is not really intended to be a quick fix up for a celebration.
It is more of a showcase of craftsmanship and creativity.
First, prep your work space. Lay down the news paper, get your bowl ready, know how many eggs your going to need for your cake recipe, and don't forget to wear washable clothes, or an apron, or both.
Next, take your egg and punch a little hole at the wider end of your egg with your pointed object. As soon as the small hole is made work your way around the edges chipping of itty bitty pieces until you have a larger hole that is to your liking. Please note that the bigger that hole is, the easier it will be to empty it, and keep the shell from cracking while it's baking.
Then turn the egg so that the hole is pointing down, stand over your bowl and shake the egg vertically very vigorously. It will take a few moments for the egg whites to find escape through the hole, but it will eventually get there and the egg will then guide itself out with the help of your continuous shaking which doesn’t have to be so vigorous now that the egg is running. If the yolk is still in tact, you will need to take a n object that can fit through the hole you have and poke a hole in the membrane of the yolk. Then repeat the shaking process. If the egg is almost empty, add water inside and shake again. Fill the empty egg with water again and give it one more shaking episode to clean it out. Do this with all of the eggs, but only shake out the eggs you need for your cake in the bowl. Switch over to shaking out at the sink to dispose of them or into another bowl if you can use these eggs sometime in the near future.
Set the now hollow shells out to dry afterwards.
