To get the perfect soft-boiled egg, place an egg in a small saucepan with just enough water to cover the egg. Bring the water to a boil and let the egg boil for 4-5 minutes. When done, remove from the heat and immerse the egg in cold water to stop the cooking process. When the egg is cool enough to handle, peel it, slice it, and place it on top of your Ramen bowl.
