Measure out and weigh all ingredients
Add vinegar to the milk and leave to sit for a minute while you prepare the other ingredients
Combine all the dry ingredients and gently whisk together
Add the egg, milk and melted butter and gently whisk to create a thick uniform batter – do not overwhisk – gently fold in blueberries
Place saucepan over medium heat and using a ¼ cup measuring cup, scoop cupfuls of batter into the frying pan
Once bubbles appear at the edges on the pancakes, flip over and continue to cook for 1-2 minutes
Serve as a stack with maple syrup and fresh blueberries
