Like, I get comments from people telling me it's weird I always try to peel potatoes like I am trying to make the worlds longest 1-piece potato peel. To me it feels way for efficient and fun to continu down a potato in 1 peel, while circling around it, instead of randomly scraping a hundred different pieces of peel off and having to reintroduce the cutter knife to the potato for every piece.
Should be worth noting that the skin of potatoes contains toxins.
Not if you remove eyes, sprouts and green parts. What you want to avoid is green flesh. If you scratch under the skin and its green pitch it.
