Korean Noodle Broth

(OPTIONAL): In a small pot place 4 eggs and submerge with water (not boiled) and bring to the boil, stir around the pot gently as the water heats up to centre the yolk. Once boiling, cook for about 6-8 minutes, for a medium egg. Remove from the pot and run under some cold water until cool enough to peel. Slice in half once cool.
