Boil the peeled and chopped potatoes for 15 minutes.
While the potaotes are cooking, add all the sauce ingredients to a tall cup and combine with an immersion blender for at least 1 minute, until it is thick and reaches an even consistency. Set aside.
When the potatoes are tender, strain and rinse them with cold water. Add them to a large bowl.
Add the onions, celery, dill and sauce to the bowl with the potatoes. Mix until all the ingredients are evenly coated in the sauce.
Top with fresh chives if desired.
Enjoy!
Notes
If you don't have an immersion blender, feel free to use a food processor or high speed blender to achieve similar results!
