This will be my first potato salad. I enjoy eating it but never tried to make it. My question related to how to cook the potatos. The recipe says to cube the potatos (red skinned if it matters) and the place in a pot, cover with one inch of water and boil for 10 to 15 minutes until just tender. A 10-15 minute boil of cubed potatos seems like a long time to me. Will the potatos turn to mush?
