Recently my wife and I and my sister ate dinner at a nice restaurant in Chattanooga, St. Johns, I think. They served a very nice sourdough potato bread. I decided to try to make some. My sourdough starter is sitting on the counter ready to use.
I used Google to find recipes on the internet and found several that were all the same. The one I choose was www.basic-recipes.com/bds/potato.htm. It calls for instant mashed potato, so I used my favorite instant potato, Hungry Jack. These are flakes of russet potato. I followed the recipe and at the end, no bake temperature or time was given. So...I turned on the convection oven to 450, put a cup of water into the cast iron frying pan on the bottom, and put the bread in to bake, essentially a cold oven start. I set the timer for 30 minutes. Then turned on the oven light. The bulb was burned out! I used a flashlight to monitor the bake process. After 15 minutes, the bread was browning a little quickly, so I turned the oven down to 350 and continued. At the end of the 30 minutes this is what we got. The bread internal temp was 200 degrees F.
Here is the crumb. The bread has a barely sweet flavor and a soft crumb but still sturdy enough to not break when spreading the butter. I served it warm. We will have more tomorrow on Thanksgiving when everybody is here.
