How to Make It
Using a very sharp thin-bladed knife, cut the salmon fillet straight down across the grain into 1/3-inch-thick slices.
In a small bowl, combine the lemon juice and wine. Arrange the salmon slices on a glass or ceramic platter and pour the lemon mixture on top. Refrigerate for 45 minutes. Pour off the liquid and pat the salmon dry. Drizzle the the oil over the salmon, scatter the peppercorns on top and season with salt.
