Smoked Whitefish Salad with Horseradish Vinaigrette

I grew up eating smoked whitefish, smoked sable, and lox. It was a traditional Sunday brunch for my family, along with toasted bagels, cream cheese, and scrambled eggs. This salad is an extension of all those flavors i crave. Serve it as a smoked fish salad for brunch or mound it on rye bread crostini for an appetizer. It would also pair with crisp Belgian endive leaves: spoon a small mound into the broad end of the canoe-shaped leaves.
