The eggs are best made a day or two in advance. Bring a large pan of water to the boil and season well with salt. Add the eggs and cook for 7 mins. Remove using a slotted spoon and lower into ice water to cool.

Mix the 150 ml soy sauce, mirin, 150ml water, 1 sliced spring onion, the ginger, chilli flakes, peppercorns and sesame seeds in a deep container. Peel the eggs and lower them into the soy sauce mix. Put the lid on the container, then chill for at least 3 hrs. Will keep chilled for up to two days.

Mix the miso, 2 tbsp soy sauce, rice wine vinegar, honey and coriander in a medium bowl. Boil the soba noodles following pack instructions and rinse well with cold water to keep them from sticking. Reserve some of the noodle cooking water.

Put the vegetable oil in a frying pan over a medium heat. Scatter in the garlic and ginger and cook for a few minutes until fragrant. Add the spring greens, stirring well until wilted, then mix through the cooked soba and sauce from the bowl, adding a little noodle cooking water to loosen. Mix until silky and coated.

Split the noodles between two bowls, then slice the eggs and put on top of the noodles. Spoon over 1 tbsp of the egg marinade. Sprinkle with a few sesame seeds and serve.
