Add sugar and cream well. Add eggs, sour cream, and orange juice. Don't worry if the batter curdles. It will come together as you add the dry ingredients. Add those now and mix until blended.
Drop by teaspoonfuls onto greased baking sheet. Bake at 350 12-15 min.
Allow to cool and glaze with a mixture of powdered sugar and orange juice. Store in an airtight container.
Notes
If you find that the cookies spread too much, refrigerate batter for 30 minutes before baking.
