Here's something that I've been making for family gatherings. You simply blend all this stuff in a blender/food processor. Don't forget to season with salt & pepper. I usually serve this with breadsticks, crackers, fresh baguette slices, olives... This makes around 6 servings...you can make it a day ahead, just make sure when you take it out of the fridge you give it some time to reach room temperature before serving.
8 ounces smoked salmon, chopped
1/4 cup (1/2 stick) unsalted butter, room temperature
2 ounces cream cheese, room temperature
3 tablespoons chopped fresh chives
2 tablespoons chopped shallot
