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.
The most effecient way is to NOT peel potatoes. Why would you ever want to peel them? Potato skin is yum and rich in nutrients, whereas the flesh is mostly carbs. By throwing away the skin, you’re not only wasting nutrients, you’re getting rid of the texture and fiber it adds.
I used to eat the skins until my kidney stone went to the lab. No more skins or spinach for me. :-( Kidney stone pain is an amazingly-effective incentive for dietary change.
