I like that idea of cooking food in boiling water with baggies. We did that kind of thing when I was working at one of those Leisure Time Resorts.
I was the weekend breakfast and lunch cook, among other things that I did there.
The eggs came in one of the gallon sized bags, and we just dropped them in boiling water until we had scrambled eggs. The hot water kept the eggs ready for me to dish up with some of the hot pancakes and bacon that I cooked to go with it.
The only time that I used the fresh eggs was when someone wanted an easy over egg, and most of the time, people happily enjoyed the scrambled ones.
One of the perks of working there was that the leftover pancake mix and scrambled eggs had to be thrown out, and I was allowed to take some home if I wanted, and give it to other workers when I didn't want it.
My dogs and I had lots of pancakes and scrambled eggs to eat !
