When you have excess eggs, making powdered eggs is a great way to put that surplus to use!When you have excess eggs, making powdered eggs is a great way to put that surplus to use! You'll want to dehydrate scrambled eggs (scramble only on a nonstick pan and add NO butter or other nonstick item as it'll make your eggs go rancid in storage). Dehydrate for 12 hours at 140 degrees. Vacuum seal to keep fresh (I put my jars in the freezer). The shells can go back to your chickens for the calcium intake; they love 'em! Recipe courtesy of Patricia Hall!
