Making deviled eggs is usually a chore and the eggs don't always come out of the shell looking pretty. I have seen these on TV and was a bit skeptical, but decided they were worth trying. I started with one egg just to test it out. The egg actually stuck to the inside a little, so I sprayed the containers with just a little bit of cooking spray and they came out perfect. So much easier to crack a raw egg than it is to shell a hard boiled egg. The task of making deviled eggs is so much easier now.
