Preheat the oven to 400.

Cut each potato in half and place on a parchment lined pan, cut side down. Very very carefully slice a sliver off of the top of each potato half so that they will sit flat after you cook them.

Bake in preheated oven for 18 - 20 minutes, or until potatoes are soft. Remove from oven, and allow to cool to room temperature.

Once cooled to room temperature, place about a teaspoon of sour cream on each potato, and a small piece of smoked salmon on top of the sour cream.

Garnish each bite with a caper.
