Q: I just made a batch of potato latkes and fried them up until crispy brown. They tasted excellent, but we stored them in the refrigerator, wrapped up and continued to eat them for a few days. After the third day, the center on some of the potato pancakes turned black. Can you tell me why or what to do to prevent it? I added lemon to the shredded potatoes while I shredded them to prevent discoloration. I used 12 large Idaho® potatoes, 10 eggs, a half cup of Matzo Meal, a half cup of high gluten flour, a tablespoon of baking powder, salt, pepper and two grated Spanish onions; I fried them in a blended oil. Could the high gluten flour have something to do with it?
