Bests & Worsts Reviews from Amazon

Well made and quite substantial. Fits flatly on the surface of the pan. The outside diameter is 4 inches and the inside is 3 3/4 inches, and is 3/4 of an inch deep. The metal handle folds down flat for storage, and has a silicone insert so your fingers wont touch hot metal. This is the perfect size for a single egg, pancake, or omelet type recipe. I purchased two sets of 2 rings, for a total of 4. This is exactly what I have been searching for. They are high heat resistant to 500ºF/260ºC, and are FDA approved. There are a couple of recipes, and use instructions on the back of the bubble pack's card. Instructions: "Place on seasoned hot griddle or fry pan, lip side down. Pour 1/4 cup pancake batter or 1 raw egg into ring. Cook until egg or pancake sets. Gently pull ring away from sides, remove and flip to set." One recipe is for "Cheesy Egg Delight", and the other for "Fluffy Buttermilk Pancakes".
