You pour an egg
into the
ring, you lift the
ring expecting a
muffin size fried egg... no, it sticks and you end up with a sloppy egg mess worse than frying the egg alone and placing it on a
muffin... good idea, horrible production.
(If you really want to ensure perfectly even cookies, you can roll out the dough, cut it
into circles with a
ring mold, and then transfer the dough circles to a
muffin tin, but it's not necessary.)
