This egg ring has 1 major advantage over others, thermal mass. When preheated it holds and transfers enough heat to cook the edge of the egg in about 10-15 seconds and stop leakage under the ring. It forms a cooked egg dam that holds back the rest of the uncooked egg. That lets you remove the ring before the entire egg finishes cooking. The ring can be set on a clear portion of the griddle to start a second egg cooking while the first finishes. Maybe a 3rd. But that serial process with just 1 ring is less efficient than several of these rings cooking a batch of eggs in parallel. There needs to be some tool to move the rings. You can do it with your bare fingers, but that is a bit hot even for those used to handling grilled items. Having the preferred method pictured would help users.If you don't preheat the ring and your griddle or pan, egg white will leak out under the ring. Hot butter or oil on the griddle or pan also helps make the seal.With a left and right cook sharing an egg griddle, a number of rings would be preheated in the center of griddle. Left cook would start a batch of eggs with several of these rings at the same time. Enough so that by the time the last egg in the batch is cracked, the first egg is sufficiently cooked to remove the ring. Left cook removes the ring and sets it in the middle. The right cook begins the same process.For a single cook, you can form a rack out of stiff wire to grab several rings at once that fits in the middle groove. Slide a rack of rings against the back wall of the grill. crack all your eggs. Wait, remove the whole rack at once if you are really good. More likely you will use grill gloves to pick them up one at a time.
