Dave Hax demonstrates an efficient way to peel a large amount of potatoes without a vegetable peeler in his most recent video. The method he uses involves slicing only the potato peel around each raw potato, then boiling the potatoes, dipping them in cold water, and removing the top and bottom halves with your hands.
This simple trick show you a speedy way to peel your potatoes without using a peeler. Great if you’ve got a lot of potatoes to peel. You need to boil the potatoes, but you could try parboiling them and then putting them in the oven if you want roast potatoes, or cutting them for chips.
