Instructions
Pour the two cups of milk into a liquid measuring cup and add the two tablespoons of white vinegar. Stir and let stand for at least 15 minutes.
In a large bowl, whisk together the flour, sugar, salt, baking soda and baking powder.
In a medium bowl, whisk the eggs, add the melted butter and sour milk, and mix together.
All at once, add the liquid ingredients to the dry ingredients and stir until combined.
Heat the griddle over medium-high heat. Add a little butter and the pan is ready for the batter when the butter begins to sizzle.
With a large spoon, gently pour some batter into the skillet to form a griddle cake. Add enough batter to the pan for one or two more.
Cook for 1 to 2 minutes while bubbles begin to form. The griddle cake is ready to flip when the top begins to dry out and the bubbles have popped. Turn the cake over and cook for 1 more minute.
In between cooking the griddle cakes, melt 1/2 to 1 tablespoon of butter in the skillet and then add the butter.
