Hydration: Effect of potatoes?
Does anybody have a good rule of thumb for calculating the hydration of a dough when it includes plain, cooked and mashed potato?
According to the USDA: Potatoes, baked, flesh, without salt (100 grams) contain on average 75.42 grams of water. That sounds right I guess, but how much of that moisture is available to the dough, and how should I adjust hydration in relation to potato content?
Thanks
