Mix all the ingredients for the pancake, one by one until well incorporated.
Heat a griddle on low-medium heat. Put a dab of butter in the pan and pour a ladle full (roughly around ¼ cup or so) of pancake batter onto the griddle.
Once the surface starts to bubble and the bubbles break, flip the pancake over to the other side.
Let cook for half a minute or so.
Remove pancake from the griddle and repeat with the remaining batter.
To make the sauce:
In a sauce pan, add the water. Crush the blueberries roughly by hand and add to the sauce pan. Add the remaining ingredients. Cook on medium heat for a couple of minutes, till the sauce starts to bubble. Switch off heat and keep the sauce aside.
