Preparation- Mix the flour, baking powder, baking soda, salt, and sugar together. In a separate bowl, whisk the egg, milk, and sour cream together. Stir the dry ingredients into the egg mixture, just until the moistened. Pour the vegetable oil on to a griddle. Heat the griddle to medium high. For each pancake, pour about 1/4 cup batter onto the hot griddle. Cook until the bottom of a pancake is golden brown and the edges begin to bubble. Turn over and cook other side. Serve pancakes piping hot with peach topping (recipe below) or your favorite fruit topping or syrup.
