The Poachpod egg poaching molds are made from green silicone and have diameter of 3" / 7.5cm. The Poachpods are designed to poach eggs, bake, and to mold. The egg poachers float and poach an egg in boiling water like a lily pad on a pond. As soon as the egg is poached, flip the non-stick Poachpod inside out and and the perfectly domed poached egg will fall out.
