Why Milk Actually Works Against You
Milk adds liquid, but it also introduces proteins and sugars that can interfere with the natural starch structure of your mashed potatoes. This is why milk-based mash often turns out either too heavy and dense or oddly thin and flat-tasting. Water is even worse — it adds no flavor and simply dilutes everything you are trying to build. The starchy cooking water, on the other hand, works with the potatoes rather than against them. It carries the flavor of the potato right back into the mash while creating a texture that is smooth without being heavy.
Professional chefs have been using this technique for decades in restaurant kitchens, but it rarely makes its way into home cooking guides. That is a shame, because it is incredibly simple, completely free, and produces dramatically better results than the traditional method.
