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 toxins exist throughout the skin, but in smaller concentration than in the sprouts and green parts. Doesn't mean that the skin is inherently unsafe to eat, but you probably should peel it if you eat potatoes regulary, or if you're cooking for children, old people or someone immunocompromised.
I think cooking goes a long way to dealing with the toxins, also. Raw potatoes are very toxic.
No, alcaloids are stable under heat, that's why you should also discard the water when cooking potatoes with skin.
Not that I ever reused the potato cooking water, but TIL. Thank you.
