I am ALWAYS asked what is in this family favourite Potato Salad - it's a very common but secret ingredient which just makes it so tasty! I am about to tell the secret now....it's liquid Maggi Seasoning! I also like to add diced cornichons, small dill pickles or gherkins as we call them in England, and diced ham as well! This recipe is also low-fat making it a guilt free accompaniment for all your Barbeques & Family gatherings! I have added some optional additions at the end - which makes it a very adaptable potato salad recipe.
