Blend the flour, sugar, baking soda, and salt in a food processor. Cut the butter into small pieces and add to the mixture. Pulse the processor until slightly mealy. Mix together the egg (beaten) and the sour cream. Add the mixture to the processor and run until well mixed. Place on a floured board and roll out (about 1/4- to 1/2-inch thick). Cut into two-inch circles. Place on lightly buttered cookie sheet and bake for 15 minutes at 375 (or until lightly browned).
