For the crêpes, mix flour, salt, eggs and milk, gradually adding water and melted butter. Leave the dough to swell in a cool place for half an hour. Pour the batter into a hot, lightly greased pan with a sauce spoon, swirl to distribute the batter in the pan and bake until golden brown on both sides. Repeat the process until the batter is used up.
For the honey butter, cream together the butter and honey and mix in the cinnamon. Pour onto plastic wrap and shape into a log. Seal plastic wrap at both ends and place in the refrigerator to harden.
Spread the honey butter into the hot crêpes and serve.
