While eggs are cooling in the ice bath, cut some small slices of salmon off that will be used to top each devilled egg. The rest of the salmon can be finely chopped into an almost paste. Set aside.
4 oz smoked salmon - divided
Once cooled and peeled, place the egg on its side and slice it in half lengthwise, cutting from the top (narrow end) to the bottom (wide end) to create two equal halves.
Scoop the yolk out with a spoon and place in a bowl. Set the egg white halves aside.
To the bowl of yolks add the finely chopped smoked salmon, mayonnaise, cream cheese, lemon juice, fresh dill, Dijon mustard, onion powder, and salt and pepper. Cream everything together with a hand mixer – see Pro Tips and Tricks.
6 tbsp Mayonnaise, 3 tbsp Cream Cheese, 1 tbsp Fresh Lemon Juice, 1 tbsp Chopped Fresh Dill, 2 tsp Dijon Mustard, ¼ tsp Salt, ¼ tsp Onion Powder, ⅛ tsp Pepper
Add the smoked salmon devilled egg filling to a piping bag fitted with the large star tip. See Pro Tips and Tricks.
Pipe the deviled egg filling into the hole left behind by the yolk. Do this for every egg half.
Top each egg with a sprig of dill, a piece of smoked salmon and a few capers.
Eggs can be served immediately or placed in the fridge covered with plastic wrap to be stored until ready to serve.
