Haha, how timely is this! I was just reading a recipe yesterday for a keto sourdough-like bread:

I thought it sounded like something worth trying, except that it uses 6 egg whites and I found myself thinking, "darn, now what would I do with 6 egg yolks?"

And this sounds perfect to try! Though hope I have enough salt, that may be a problem.
