Make them the night before, fry in the morning.
For 9 pancakes
In the morning mix in sparkling water a little at a time until you have a batter which is just pourable.
Fry in batches in a generous amount of oil, don’t let the pan get too hot. One ladleful of batter, with a few blueberries dropped on top, per pancake. Flip the pancakes when the top starts to bubble and set.
Have the rest of the blueberries on the side and drizzle on some maple syrup.
