I am a novice too, but i have been waterglassing eggs for about a year. Here's what i've learned - Dont use the poopy eggs for waterglassing. Use those for eating now, or preserve them by freezing instead. You want to select the cleanest eggs for waterglassing. The bloom comes off easily, so dont use hydrogen peroxide or anything moist. Brush nominal bits off with a dry cloth. I had a big 2 gallon beverage dispenser i opted to use for the project. The Lime solution will damage and etch the glass, so don't expect to use your jars for another purpose later! For me a wide mouth quart jar was too narrow to easily get eggs in and out, i think thats why some use a bucket. I used glass so i could see what was happening inside the jar! i did have some eggs break (maybe had a bloom problem?) and my info told me to discard the lime solution and start over if that happens. Second time, none broke. I keep mine covered but I dont think having a seal matters. The eggs just need to stay submerged.
i use a ladle to get eggs out to use, or I use a rubber glove on my hand if Im going to reach into the solution (thats easier, frankly!) The solution is very caustic. You also want to wash the eggs well before cracking so none of the lime solution gets in your food.
My problem now is that i want to do a new batch of waterglassing but I still have a lot of eggs from my last time. Some are over a year old. The yolks break very easily so i wondered if they are safe or deteriorating? I scrambled some and they were fine; i also baked with some and the muffins turned out very nice. Then i broke open a few and there seemed to be cloudiness in some of the white near the yolk. I discarded those. I wish someone would post a photo of what it looks like when an egg has deteriorated too much to use. I have no sense of smell, so I cant tell that way! Id appreciate feedback if anyone knows! Good luck! Im glad to hear others are using this method!
