Peeling potatoes before boiling can make a big difference in their texture and overall mouthfeel. Imagine taking a bite of a lumpy, uneven potato versus a smooth, silky one - it's a game-changer. By removing the skin, you're also removing any potential impurities or excess starch that might make your potatoes feel gluey or unappetizing.
On the other hand, peeling can also lead to a loss of nutrients - many of the vitamins and minerals in potatoes are found in the skin, so stripping it away means you're losing out on some of the good stuff. It's like throwing away the best part of the deal. But, if you're looking for a super-smooth mash or a perfectly cooked potato salad, peeling might be the way to go.
