Perfectly Cook and Slice Hardboiled Eggs Every Time
The Norpro Egg Perfect Egg Timer is an inexpensive and amazing little gizmo. It really works. You just put this heat sensitive plastic egg in the boiling water with your real eggs, and it changes color at the same rate as the eggs. It's easy to read the scale and get perfect soft, medium, or hard boiled eggs every time, no matter what altitude you are at or how many eggs are in the hot water bath.
And when it comes time to sliced your hardboiled eggs, skip the knife and go pro. An egg slicer has wires that slice through the egg producing neat and uniform slices in seconds. I even use mine on mushrooms and bananas.
