Ever accidentally overcook the taters and make mashed potato salad? Some people actually like it that way. I'm a cube guy.

Try cutting before you cook the potatoes. They cook faster that way. (of course if you've been making the salad for decades, you can probably do it in your sleep----and a change like that would throw everything out of sync!)
