1. For the pancakes, stir flour, sugar, baking powder, baking soda and salt. Stir in the egg, milk, sour cream or yogurt and melted butter just until blended (a few lumps are OK). 
  2. Heat a griddle on medium and grease lightly. Ladle the batter onto griddle and place a sprinkling of blueberries onto each pancake. Cook until golden, turn carefully and cook until golden on other side. Remove and keep covered and warm until ready to serve with blueberry syrup. 
  3. For the syrup, heat syrup and brown sugar, stirring to dissolve sugar. Add the blueberries and cinnamon and bring just to a simmer. Remove from heat and serve.
