Melt the butter and remove from heat to cool slightly. Preheat your griddle, waffle machine, pan, etc. Remove half the yoke from the egg and beat with the sugar. Add the flour and beat all until well blended. Add the butter and beat until all lumps are gone. Pour the batter onto the cooking surface and cook until light brown (about a minute in a waffle iron). You will need to flip if you are using a griddle surface or pan. After removing from the heat, quickly shape into a cone (or bowl) and allow to cool.
