1. Cover the shredded leek in very cold water.
Cook the bacon in a frying pan over a medium heat until brown and crisp.
Drain on kitchen paper and add the butter to the pan.
2. Add the scallops and cook for two to three minutes on each side (or one minute for little ones), until nicely browned, then remove from the pan.
Add the white wine or sake to the pan and cook off the alcohol.
3. Scrape any bits off the bottom of the pan, then tip everything into a saucepan.
Add the stock and mirin, and bring to the boil.
Add the dashi powder and some salt, taste and adjust the seasoning as necessary.
4. Slice the scallops horizontally into thirds (or leave whole if little), and roughly chop the crispy bacon.
5. Bring a separate saucepan full of water to a rolling boil and cook the ramen according to the package instructions.
Pour or ladle the broth into deep bowls, drain the noodles well and place in the broth. Drain the shredded leek.
6. Top the noodles with the eggs, shredded leek, chopped bacon, sliced scallops, chilli oil, if using, sesame seeds, pea shoots and some black pepper.
