Slightly off topic, but its relevant to the last post.
Instead of an egg, as in a fresh egg, could this be done with powdered eggs? I've got a couple backpack trips planned for this summer and I don't really want to try to carry fresh eggs and risk having them break or go rotten so I'm going to be using powdered. I wonder if a guy made the equivalent of one fresh egg with the powdered substitute and stirred it in as you explained if it would still work the same way? I know that in egg drop soup the key is to constantly stir while you are slowly pouring the beaten eggs into the pot, so that would probably be the case with this too.
I might try that with Velveeta cheese since that doesn't require an Engle fridge in your back pack too.
