I was looking in my Encyclopedia of Country Living and found instructions for drying eggs. I've seen egg powder in recipes like for homemade pancake mix and such, but it isn't a item readily available in stores. It says: Beat fresh whole eggs thoroughly. Line a baking pan with foil and pour egg in to just 1/8 inch deep. Dry in oven or dehydrator at 120 degrees for 24-36 hours. Turn the egg over and dry another 12-24 hours. Break it in pieces and dry longer if needed. Crush into powder with a mortar and pestle, a food processor, or a rolling pin. For baking, substitute 1 1/2 Tablespoons egg powder plus 3 Tablespoons water for each large egg. To do scrambled eggs, combine equal parts egg powder and water. It says it will go rancid in 3 to 4 months if not used, but it sounds like a nice stable to have for camping or for emergency food stock. I may give it a try.
