Demographics were very different back then. Nowadays we have one person households. Also nowadays nobody peels potatoes anymore. I honestly wouldn't know how.
Don't eat green potato skins, or sprouted eyes.
Don't peel potatoes, they're delicious and have ++ nutrients.
On the upside, Chips(fries) taste SO much better when they are just made from fresh potatoes and olive oil.
