Put water on to boil for the eggs if using. Add the curry paste, sesame oil, garlic and ginger to a large pot and heat over a medium heat for a couple of minutes until starting to sizzle and get fragrant.
You'll want to put your eggs in the boiling water at this point. Pour in the stock, coconut milk, white parts of the spring onions, ramen noodles, mushrooms, lime juice, soy sauce and pak choi and bring to a boil.
After a couple of minutes, when the noodles are nearly cooked, add the edamame and cook for another 2 minutes then serve topped with a boiled egg if desired and the chopped green parts of the spring onion plus lime wedges.
