Scrambling an egg inside its shell is nothing new, but Windell at Evil Mad Scientist Laboratories wanted to go the extra step of making a complete omelette without fully opening an egg. Here's how he planned to do it:
1. Puncture the egg with a small hole (1-5 mm)
2. Scramble the egg inside the shell, through that hole
3. Plug the hole (maybe with egg) so that the egg won't leak
4. Boil the egg for a few minutes to cook the outside part alone
5. Use a syringe to extract the (still-liquid) center
6. Fill the center with some appropriate filling
7. Plug the hole again, so that the egg won't leak
8. Return the egg to boil, to cook the raw part that is contacting our filling
9. Retrieve the egg and serve it
That turned out to be much easier said than done, and Windell had to ultimately resort to cooking the eggs in vacuum-sealed bags. At the end of the post, he proposed a number of advanced recipes, such as inverse Scotch eggs -- that's sausage injected into an egg.
