There are some gadgets that are especially appealing to a certain customer. This customer is high-maintenance, particular, demanding, and won't let you console or talk sense into them. These people buy egg poaching apparatuses and rotary cheese graters.
The egg poaching crazies are concerned with so many things: construction and materials of egg poachers; quantities of eggs that can be poached in a poacher; ease of clean up of a poacher. They fret and bemoan the egg poachers available on the market. "Why hasn't someone made a better egg poacher?!?!" And I have learned from experience that the worst thing you can do is suggest they just make poached eggs in a pot. These people don't want solutions; they want gadgets!
The rotary cheese grater crazies want 1) a grater "like at Olive Garden," 2) a grater "like their grandmother had," 3) a grater that will allow them to grate cheese without actually having to touch it. Despite the fact that we usually have one or two styles of rotary graters, they are rarely pleased because they have a fantastical vision of a grater in their minds.
I just had a poached egg for breakfast. I made it in a sauce pot. It was fucking fantastic and easy.
