Place the eggs in a small saucepan and cover with cold water by 1 inch. Set over medium high heat and bring to a boil. As soon as the water is boiling, remove the pan from the heat, cover and let sit for 10 minutes.

Remove eggs from the water with a slotted spoon and transfer to a bowl filled with cold water and ice. Let the eggs rest in the ice bath while you prepare the remaining ingredients.

Combine the mayonnaise, sour cream, dijon mustard, shallot, capers and dill in a medium bowl. Peel the eggs and cut in half lengthwise. Transfer the yolks to the bowl. Whisk all ingredients together until smooth. Chop the egg whites into a medium dice. Fold into the mayonnaise mixture. Season to taste with salt and pepper. Be sure to taste first! Capers are quite salty and you may not need any additional salt. Serve immediately or cover tightly and store in the refrigerator for up to three days.
