Boil eggs until the yolks are firm (see our guide), then chill in the fridge. Once eggs are cold, carefully peel them, then slice in half, cutting lengthwise. Clean your knife between eggs for smooth slices.
Use a teaspoon to carefully remove the yolks, transferring them to a mixing bowl.
To the mixing bowl, add the mayonnaise, sour cream, seasoning, spices, and finely chopped dill, and use a fork to mash everything together, then stir vigorously to well-combine.
Taste, and adjust the seasoning as you like.
Spoon the creamy egg mixture back into each egg white; use a piping bag if you wish.
Tear the smoked salmon into eight narrow strips, roll each up, and place them on the creamy egg mixture; add a teaspoon of caviar to each egg, and garnish with a sprig of dill.
Serve with Champagne or shots of chilled vodka as my family did.
