In the bowl of a stand mixer fitted with paddle attachment, beat together cream cheese, sour cream, horseradish, and lemon zest until well combined. Add trout to the bowl and let mixer break it down a bit (but be careful to stop before the dip is completely smooth—you want to see that there are still some large chunks of trout). Fold in chives by hand. Serve with Fancy Saltines (recipe below).
