I sliced some raw potatoes on Wednesday night when I was making homemade pizza. We didn't use them all for the pizza so I put the leftovers into a container in the fridge covered with water. I changed the water on Friday morning and again on Saturday night. The potatoes seem fine tonight (Sat) and I'm hoping to make hash browns from them for breakfast tomorrow. DH & DD are a bit queasy on the idea since they've been in the fridge so long. Tiven asked how I would know if they went bad, and I said that I thought they would smell sour. She said she thought things could go bad without smelling sour. I can accept that logic in principle, but for some reason I don't think it applies to sliced raw potatoes kept in fresh water. Anyone know for sure? This brilliant girl of mine has conceded that someone on Pg.org probably knows better than some general doofus posting something that comes up on a Google search.
