Check out this amazing site devoted to egg cups. They are more art than serving piece here, which seems only right. I have yet to ever soft-boil an egg, set it in an egg cup, and crack the top off with a spoon (ugh! It really doesn't appeal to me!) but I have found that the absolute best way to display an egg that has just arrived from the henhouse is to set it in an egg cup. We have three; I wish we had more.
This blog is in Spanish, and as far as I can tell, the bloggers are in Brussels. It looks like people are sending them egg cups from all over. Check it out here:
