This is a recipe I have used for over 30 years. Any family potluck dinner we have, I am always on potato salad duty. I bring a double batch of this old favourite. It always goes fast and I have given out the recipe many times over the years. I cheat a little and make a lower-fat version for my family, but always make the full-fat version for company. New, red potatoes may be used with skins on. This is a chunky one, not meant to be mashed.
