Take care not to overcook your potatoes – you don’t want them overly mushy.
Mix mayonnaise, vinegar, mustard, chicken stock and salt and pepper in a large bowl.
Add potatoes, celery, onion and stir gently.
Stir in eggs.
Cover and refrigerate at least 4 hours to blend flavors and chill.
Potatoes love to soak up all the mayonnaise, so if you noticed your salad is just a little dry when you are ready to serve, just add a little more mayonnaise and chicken stock and it will restore the creaminess of your potato salad.
