It calls for hard-boiled egg, rather than raw egg, in the dough. It's sort of an old fashioned technique you don't hear about anymore. I tried researching the topic, but I couldn't find any information or history. It sounds kind of gross, doesn't it?
I had never heard of using hard-boiled egg in a cookie, so I had to try it.
These were very good cookies, and oh-so crumbly. Mine look more rugged than their cookies, and I think it's because I didn't process everything enough.
Give them a try and let me (or them) know what you think!
This is a great way to use up all of those leftover Easter eggs. Also, don't worry; you can't see the egg bits in the cookie.
Mmm, Ghiradelli bittersweet chocolate chips...
Sorry, that's all I have for now.
