This oven method, of cooking eggs in the shell, is not only fool proof, but the eggs come out absolutely perfect and you can make a ba-jillion at once!!
How long you bake the eggs depends on the size of eggs you use and how hot your oven runs. I used large grade A eggs and cooked them for 25 minutes. If you are concerned about it, just run a "test egg" to gauge how long to cook them.
When the eggs are done, use tongs to put the eggs into a bowl of ICE water (for 10 minutes) to stop further cooking.
NOTE: After the eggs are cooked, you MIGHT find SOME eggs that have brown speckles on them, but don't freak out; these little specks will dissolve when you put the eggs into the ice water. The next photo is before and after the ice water bath.
Not only is this a great way to cook Easter eggs in bulk, but the eggs are delicious!! The yolks are bright yellow and the whites are very tender (not rubbery like boiled eggs can produce).
Where has this cooking method been all my life!?!?
