When cool, add celery, chives, nuts and additional dressing. Taste and adjust seasoning.

For the Dressing: Place shallot, mustard and lemon juice in blender or bowl of food processor. Process until shallot is pureed. Add salt, generous grindings of pepper and blend. With machine running, add oil in steady stream. Dressing should be a little salty as potatoes absorb a lot of flavor.
