The Secret

My yellowed yard-sale paperback circa 1972 had a cursive note scrawled across the cover: Very good potato salad page 65. So naturally I had to read that recipe first. I quote:

The secret to a really good potato salad is the preparation of the potatoes:
Boil them before you peel them, chill them before you slice them.
If you follow those simple rules you will always have an outstanding potato salad.

I tried it, and it's true, and the potatoes are sharp-angled cubes versus amorphous blobs.
