Ingredients

3/4 pound (3 sticks) unsalted butter, room temperature 

1 1/2 tablespoons minced chives 

1 1/2 tablespoons finely chopped fresh dill 

1 1/2 teaspoons freshly squeezed lemon juice 

1 1/2 teaspoons coarse salt 

1/2 teaspoon freshly ground pepper 

1 1/2 loaves grain bread, sliced 1/4 inch thick 

1 1/2 pounds smoked salmon, thinly sliced 

Preparation

In a bowl, combine the butter, chives, dill, lemon juice, salt, and pepper.

Lay out the bread slices; spread with prepared butter mixture. Top half the slices with the smoked salmon. Lay remaining slices, buttered-side down, on top of the salmon. Place sandwiches on a baking sheet, cover with plastic, and place in refrigerator until the butter is cold, about 30 minutes.

Transfer sandwiches to a cutting board. Trim crusts from sandwiches, and cut in half to form thin rectangles. Serve chilled.
