The good news is that there was no odor. That was my fear. That there would be some horrible egg gas released. That's why I was worried about simply tossing them into the trash because I didn't want them to explode and release "agent egg" all over my kitchen. But one exploded all by itself, and it was the NON mutant one! Or at least the less mutant one.
... It's always the quiet ones.
I think that because it was unable to ooze, it couldn't handle the internal gaseous pressure anymore. I'd actually considered that the lack of ooze on that one might lead to exactly this outcome, but then I ignored that thought. After all, that's the one that looked more normal (There's a life lesson in there...)
Fortunately, I'd deliberately kept them in a small door compartment so the damage was contained. There were a few minor splatter marks but the rest stayed within a little pop out module that I soaked, washed, and white vinegared for about an hour. Then the module was returned to its former location in the refrigerator door.
It looked like caramel. Really. In both color and viscosity. And again, much to my surprise, there was no odor. No I didn't take a picture - again. I considered it but my urge to clean ASAP won out.
I know what you're thinking. You're wondering where the other egg is? It's in the trash. Hey, with the threat of rotten egg odor gone, what do I care if it explodes in there!
