Sift the flour into the bowl, add sugar and salt. Mix baking soda with vinegar then add to flour. Add eggs and mix until smooth. Add milk and stir thoroughly, to avoid lumps. Add the vegetable oil and stir again. Mix until smooth and well blended.
Heat a lightly oiled frying pan over medium heat. Pour the batter into the pan for each pancake. Fry on both sides until lightly brown. Serve hot with butter or caviar. Enjoy your meal!!!
