Mix everything together, beating well to ensure there are no lumps. Allow to stand for 15-20 minutes covered.
When you are ready to bake the pancakes, mix the batter again and if it’s too thick, add a bit more water. It needs to be quite thin, only a little thicker than pouring cream.You’ll see if you bake the first few if the batter is too thick, the pancakes need to be very thin and almost lace-like.
Heat the pan and spray with cooking spray and add 1 teaspoon of oil.
Add ladle-fulls of the batter to the pan and allow to cook before flipping. Keep the pancakes warm on a plate set over a pot of simmering water.
When you're ready to serve, sprinkle some of the cinnamon sugar over the pancakes and roll up.
Serve with fresh lemon wedges.
