A new word to me - it means the collecting of egg cups. I notice that the useless gadget thread has many egg cup posts, pro and con. I've become, if not actually obsessed, then definitely converted.
Several months ago, with a wet hand, I dropped and cracked a 1970 Figgjo pottery pint-sized pitcher which was used daily to microwave water for tea or instant coffee. It had nostalgic value, being one of the first things I ever bought based purely on aesthetics - college senior visiting Toronto, $9 at Georg Jensen. I loved its proportions and it turned out to pour perfectly, unlike many a Pyrex measuring cup whose lips drip. So I went on eBay looking for a replacement (not yet obtained), and came upon the Figgjo egg cup.....a little piece of perfection! It's an egg-shaped plate, roughly 4x5", with a bermed well at the narrow end that firmly cradles the egg. The rest of the plate is enough space for a little mound of salt and the discarded bits of shell. Now, I hadn't eaten a soft-boiled egg in decades and recalled not liking them. But this object is just so aesthetically pleasing that I couldn't resist. No impulse, either - it took 2 months to find a single one at a reasonable price (I didn't NEED one, much less 4!). Once my treasure arrived, of course I needed to try it out, and discovered that with the free-range eggs I now buy, I actually love soft-boiled eggs.
Just for the heck of it, I had searched all egg cups on eBay - there were thousands of them, in many hundreds of styles reflective of differing cultures. No surprise, then, that some German-made ones were sleek, stainless steel versions of my ovoid, bermed-plate Norwegian gem. British ones in the shape of the heads of government and the royals. Even Nascar egg cups! Books on collecting them are also available - who knew?
