Bought a box of ramen from the Nartia Airport before returning to Singapore. Consist of 4 servings for about 1000Yen. It comes with 4 packs of noodles and 4 packs of sauce. The eggs served in Japan in the ramen is hard boiled with the yolk still soft. After doing some investigations through some books and internet, I managed to find the technique of making the eggs. A rough guide on how long the egg needs to be cooked depend on how cooked you want the yolk to be.
Water should be brought to a boil before gently submerging the egg into the boiling water. Start timing only when the egg is submerged into the boiling water.
