Preparation
Make-ahead: The cream cheese mixture can be made up to 1 day ahead, covered, and refrigerated. The relish can be made up to 4 hours ahead, covered, and refrigerated.
1.To make the relish, in a small bowl, stir the onion, capers, lemon juice, dill, and mustard seeds together. Season to taste with salt. Set aside.
2.To make the sandwiches, in another small bowl, mix the cream cheese, crème fraîche, and chives to blend. Season to taste with salt.
3.Spread the cheese mixture over the toasted slices of pumpernickel and baguette. Cut each slice of pumpernickel bread on the diagonal in half. Top each piece of bread with 1 salmon slice and then with a generous spoonful of the relish.
4.Transfer the tartines to a platter. Using a Microplane grater, finely grate the zest of the lemon over them and serve immediately.
