In a small bowl, mix salt, sugar, pepper, dill weed and seeds. Sprinkle
about 2 tablespoons of the mixture over the bottom of a shallow glass baking
dish.
Place salmon, skin-side down, in the dish. Sprinkle with remaining salt mixture.
Cover with plastic wrap and place a weight on the fish. Refrigerate for 48
hours,
spooning the marinade over the fish each morning and night. To serve, remove
salmon from marinade, scrape away marinade and pat fish dry with paper
towels.
Place skin-side down on a cutting board. With a sharp knife, shave the
salmon.
Serve on toast rounds or crackers with mustard sauce.
