First, crush the peppercorns with a mallet or by hitting them with the back of a skillet.
In a medium-sized bowl, combine the peppercorns, salt, brown sugar, and the vodka, stirring to combine and the mixture is of wet sand consistency.
Place a cooling rack on a rimmed cookie sheet.
Then place the raw salmon, skin side down, on the rack.
Start by pressing ½ the salt mixture on the meat of the salmon.
Add ½ the fresh dill, followed by the second ½ of the salt mixture and finishing with the last of the fresh dill.
Tightly wrap the entire tray, pan, rack, and salmon in several layers of food wrap. (make it as tight as possible.
Allow the salmon to cure, in the refrigerator with something pressing down on it for 2-3 days. (yes DAYS) I will place a second baking sheet on top of the wrapped salmon and something heavy like a couple of jars or even a brick.
Once the days of curing is complete, unwrap the tray of lox, remove all of the dill and sugar/salt mixture by running it under cool running water.
Slice the lox with a long sharp knife and serve with your favorite accompaniments.
