My maternal grandmother used to make this. Not sure if it's her recipe or not but she is where I got it from. So I post it in her memory.

Replacing instant potato flakes with whole mashed potatoes alters the starch ratio and introduces excess moisture that requires reducing the liquid component by roughly twenty percent. Dehydrated potato flakes supply a standardized starch concentration that absorbs hydration predictably during the initial dough mixing phase. Wild yeast cultures cultivated with commercial potato flakes exhibit distinct fermentation characteristics compared to traditional flour-and-water starters. The added starch provides sustained nourishment for the microbial ecosystem, resulting in an active agent that reliably produces three distinct loaves from a single batch of dough.
Potato flake sourdough emerged as a popular baking method in rural American households during periods when preserving perishable fresh yeast was impractical. Dehydrated flakes offered home bakers a stable, shelf-stable base that maintained continuous cultures on the kitchen counter without frequent purchasing of commercial packets. This technique bridged the gap between traditional sourdough maintenance and modern convenience baking. Generations of bakers utilized potato water or flakes to enhance moisture retention in everyday sandwich loaves.
Managing the fermentation schedule requires strict adherence to environmental timing and temperature controls. Leaving the starter on the counter for three days establishes the primary microbial colony before cold retardation in the refrigerator. Feeding the culture every three to seven days prevents the acidity levels from destabilizing the yeast population. Allowing the jar to sit at room temperature for twelve hours prior to mixing ensures the organisms reach peak activity before encountering the six cups of unsifted flour.
Assessing structural readiness relies on physical inspection rather than internal temperature readings. The unbaked dough must rise until it visibly clears the rim of the greased baking pan before entering the oven. Visual cues during the thirty-five minute bake at 350 degrees include a deeply golden crust and a hollow sound when the bottom of the loaf is tapped. Proper cooling on a wire rack allows the interior crumb structure to set fully before slicing.
