Add the sour cream, seasonings, Dijon, scallions, and capers to a mixing bowl.
Stir well and add a teaspoon of caper juice to thin out the sauce. * see notes
Chop the eggs to your desired size and add to the sauce.
Using a flexible spatula and gently fold the eggs in until well combined.
Taste the salad and adjust the salt and pepper. (the capers and caper juice added enough salt for us)
Notes
Caper juice is needed to thin out the sauce, but it’s very salty. I added three teaspoons, but you may like it with one teaspoon. Add a little a time until it tastes good to you.
