Eggs held at a low, steady temperature until the white barely sets to a soft custard and the yolk stays warm and runny. Named for the hot-spring baths the technique imitates.

Method
Bring the water to the boil in a large saucepan, then take it off the heat and let it stand for 2 minutes so it settles at around 70°C.
Lower the eggs gently into the water using a slotted spoon, cover the pan, and leave them completely undisturbed for 20 minutes, topping the pan with a lid to hold the temperature.
Meanwhile, stir the soy sauce and mirin together in a small bowl to make a light dipping sauce.
Lift the eggs out with the slotted spoon and crack each one into a small bowl so the soft white and runny yolk slide out together.
Spoon a little of the soy and mirin sauce over each egg and scatter with sliced spring onion to serve.
