Breaking news: This just in from Pike Place Creamery's Nancy Nipples... after more queries on that burning question about breaking yolks, the milky detective came up with a few more possibilities:
Maybe pan was too hot.
The membrane around the yolk is delicate and a lot of jostling on the way home could’ve broken it.
When a hen starts laying again after winter and/ or when a young hen just starts laying their yolks are very fragile.
Could have to do with what is in their feed.
Finally, she dismissed the egg is old theory, saying "I am having a hard time believing that eggs you purchased at a Farmer’s Market would be old."
But then, yesterday, I stopped by the Creamery to ... pick up a dozen eggs, which the cashier decorated with a clever illustration... pictured above. And I told her those two were the only yolks that broke: "Well, then, they could be old. When I raised chickens, they used to hide their eggs. They were very sneaky."
The bit about the changing of the season makes the most sense to me. Oh, and, when I buy eggs from the Creamery, I like to get the small ones. It's one of the few places that sells them. I don't know about taste. I just like the way they look in the pan. I'm frying up a couple for breakfast.
Does size matter? Do you always go for the extra large?
