An egg shaper is a kitchen tool designed to mold eggs into specific shapes while they cook. Typically made of heat-resistant materials like silicone or metal, these shapers come in various designs such as hearts, stars, animals, or basic circles. They are placed in a frying pan or on a griddle, and the egg is cracked into the mold, allowing it to cook into the desired shape. Egg shapers are popular for adding a fun and decorative touch to breakfast dishes.
