Add the milk, sourdough discard, egg, and melted butter to the dry ingredients. Stir until just combined. Batter should be lumpy.
Prepare griddle or skillet with oil or butter and set griddle to about 300 degrees or medium heat.
Pour batter in hot pan/griddle. Add any topping at this point. When the pancakes start to form bubbles on the top, flip.
