Place a stiff piece of cardboard directly on the top of the mold. Bracing one hand on the cardboard and the other underneath the mold, quickly flip it upside-down so that the egg halves are now resting on the cardboard. Quickly remove the moldyou now have two beautiful sugar egg halves. Do the same with another piece of cardboard and your egg base, if you are using one.
At this point, the egg halves need to dry out a little before you can use them. You can let them sit at room temperature for about an hour, or you can put them in a very low oven. I recommend setting your oven to 200 degrees and leaving them in for about 25 minutes.
