Pat the salmon dry and season generously with the salt and several grinds of black pepper.
In a large skillet, place the white wine or broth, water, lemon slices, dill sprigs, and capers. Place salmon pieces on top, skin side down.
Bring to a simmer and cover. Cook 7 minutes for thin salmon and 10 minutes for thick salmon, until the fish is tender and cooked through and the internal temperature is between 125 to 130 degrees Fahrenheit when probed in the center.
Remove from the pan and place on a platter. If desired, serve with additional capers, fresh lemon slices and dill sprigs.
