I formerly followed the sourdough recipes from one of the top 40 sourdough influencers, but after taking a year off I wasn't finding success and the recipes weren't working the same after I left the East Coast. This cookbook was developed in the same area that I now live, which absolutely SAVED my sanity and helped me understand my new climate. I've had successful bakes EVERY time now and I most certainly consider Sourdough Sparrow in league with those other influencers!
