when I met my wife she peeled potatoes using a paring knife. With the blade facing towards her hand. Cause thats how her mom did it.
never mind the fact that when you peel potatoes like that, you lose literally 50% of the potato. Potatoes are cheap. My concern is fuck, I don't want my kids growing up thinking thats a reasonable way to peel potatoes, I want them to still have all 10 fingers when they leave home at 18.
Finally got a really nice peeler and after she watched me use it a couple of times she switched over and never looked back.
Cooking, man (and especially the knife skills part). Its the only skill I can think of where people will do shit retardedly backwards and say "but my mom did it this way!"
I agree with your basic premise that peeling with anything but a speed peeler is a fools game. Yet, as Lanx pointed out. Nearly every one of us above a certain age learned it the other way; nearly every media depiction of peeling was via vegi knife, and don't forget, the speed peeler was only invented in 1947.
Clearly this is some combination of the tech getting better *AND* "luxury" items making their way to Average Joe over time.
