Ask Dr. Potato

Q: Do Ama Rose potatoes store well over a long period of time?

Q: Hello! Tonight we fried some Idaho baking potatoes as chips. When I was peeling them, I noticed some of the ones we used had green under the skin and the eyes had started to sprout. Unfortunately, the potatoes weren't properly stored, but not much I could do about that other than peel and prep for use as chips. When we went to eat them, we noticed the chips had a bitter taste to them. We used new, unsealed canola oil in a dutch oven configured as a deep fryer. The temperature was held between 320 and 360. and chips were cooked for about 5-7 minutes. The chips were not burned, had been rinsed, soaked for an hour+, and dried before cooking. Any suggestions as to why they were bitter? I know about solanine in the skin but figured peeling would remove the bitterness. Does the solanine permeate the potato?

Q: Do potatoes need to be on plastic wrap or could it be parchment paper (to freeze)?

Q: In the 50s & 60s, our baked potatoes had a thick skin. For a person that 'eats the skins', they were fantastic. Starting in the 70s, and definitely in the 80s, thick skins were no where to be found. I'm guessing the restaurant trade bought them, leaving us with only thin-skinned potatoes. Do you know why potato skins are not as thick as they once were?
