Into a zipper-lock bag, pour salt, sugar and dill. Squish around until combined. Add vodka, squish around some more. Add salmon to the bag. Rub and press some of the marinade over the salmon flesh. Press the two pieces together sandwich style. Rub the rest of the marinade over the skin side of the salmon. Seal the bag. Place in the refrigerator overnight.
