In a large bowl, combine the milk and white vinegar. Let this set for 5 minutes to sour. Set aside.
In a small bowl, combine the flour, sugar, baking powder, baking soda, and salt. Set aside.
In another small bowl, combine the egg and melted butter. Mix it into the soured milk.
Mix in the dry ingredients. Do not overmix. If you see a few lumps, that is okay.
5.On top of the stove, heat a large skillet to medium heat. Spray or grease the skillet with some butter.
With a large spoon, pour pancake batter in rounds onto the heated skillet and spread the batter with the back of the spoon. It is a fluffy, thicker batter. When the sides of the pancakes are bubbly, flip the pancakes and cook that side until it's a light golden brown.
Serve immediately with your favorite topping!
