Taken from an ad for Hellmann's Dijonnaise Creamy Mustard Blend. My mum lost this recipe recently and it turned into a bit of a crisis when we couldn't find a comparable one online, as this is the best one we've found (and just about the only potato salad I'll eat), so when we found it again, we agreed that it should be preserved on here in case it goes missing in the future!
- In a large bowl, combine first 6 ingredients.
- Stir in potatoes, celery and onions.
