I finally got around to trying powdered eggs. I’ve been meaning to do this for a long time, and got a bit of time to experiment. I’d always heard powdered eggs were bad, and I see why. To start, I bought a #10 can of Scrambled Egg Mix from BePrepared. I followed the instructions, made a small batch that looked great but tasted nasty. I can’t really say what specifically makes it bad, maybe salt but it’s just this weird unnatural flavor combined with a rubbery texture. I tried using less water to combat the latter, and it improved things but only marginally. It went from vile to “no seconds for me, thanks”. It was like a dry Egg McMuffin egg portion, puck like but oddly far more edible. You could make a sandwich out of it and it would be OK.
The Contenders

I read some Amazon reviews of powdered eggs, and the consensus was “Ovaeasy” is the best. Got a small packet of those, and yes we have a winner. They are very close to real eggs in taste and texture, and pretty good to eat. I fed some to my wife, who said “I’d eat them if I was starving” which means they were OK. I finished the whole portion, which I could not do with the other product. Glad I didn’t buy a lot of those!
Speaking of breakfast, I also tried the Mountain Home Bacon and Eggs in a pouch. That was fair, I ate it but it’s not quite as good as Ovaeasy. It’s way easier to prepare, no dishes or fooling with whisks and pans.
