Who knew about egg coddlers?

After Lisa, Jerry and I climbed Mt Lemmon and then had our mid-morning double espresso, I found an estate sale at the base of the mountain. I stopped in, and although most items had been sold, I found 2 porcelain egg coddlers for $3. I had a couple of bucks in my pocket so I took a chance. I came home, found a recipe and cooked up two eggs. What a surprisingly tasty little package of protein! Have you ever cooked with egg coddlers? Who knew?
