Royal Industries recommends using its 4” stainless steel egg ring (ROY ER 4) when making sandwiches for customers on the go. Egg rings are a valuable tool in any kitchen home or commercial especially at breakfast time. When cooking breakfast sandwiches or adding a fried egg to a burger an egg ring keeps the egg white from running willy-nilly across the frying surface. This makes the egg thicker and perfectly round which is extremely convenient when it"s paired with English muffins or biscuits in a breakfast sandwich.
