This is a product nobody really needs—an egg separator. There are a lot of these in stores, and here’s one by Kuhn Rikon that costs $16. And has four parts to wash.
You don’t need this if you know a simple trick: Use your fingers, over a bowl. The whites drip down and the yolk stays behind in your hand. Or use the two halves of the shell over a bowl, sliding the yolk from one half-shell to the other while the whites fall into the bowl. It’s super easy, and you’ll have nothing but your hands to wash.
