Sourdough Apple Pancakes

Mix flour and milk together until milk is absorbed and flour is moist. Let sit for 20 minutes to allow gluten in the flour to develop.

Add sourdough starter, sugar, butter, baking powder, cinnamon, and salt to the flour mixture; stir well. Stir in apple slices.

Heat a lightly greased griddle over medium-high heat. Drop batter by large spoonfuls onto the griddle and cook until center is bubbling, about 3 minutes. Flip and cook until browned on the other side, 2 to 3 minutes. Repeat with remaining batter.
