This was the first time I have used the custom settings on my Zo and I'm glad I still had the book, lol. I had to make the starter and for that I used Dawson City Sourdough Starter and Sourdough Bread. Once the starter was ready I used this ABM recipe to make make the bread. It came out quite nice with letting it work overnight and made a fab roast beef sandwich for lunch. We'll have more with tonight's dinner. It has a nice texture and the crust was chewy, not crisp or hard. If you have Zo machine give this a try.
