Prepare a bowl of ice water and set it by the stove. Bring a pot of water to a rolling boil and sprinkle in a pinch of salt. Add 100 g bean sprouts and the thick stem part of 30 g Oriental spinach to the pot and boil for 30 seconds.
Submerge the leaves of the spinach and boil for another 30 seconds before transferring them to the ice water bath. Set aside for later.
Add 1 tbsp ground sesame seeds, 1 tbsp smooth peanut butter, and 1 tsp Chinese-style chicken bouillon powder to a heatproof bowl or jug. Measure out 500 ml freshly boiled water and add a splash to the bowl.
Whisk until smooth, then gradually add the rest of the water while mixing and set it by the stove for later.
Heat a large wok over medium and add 1 tsp butter and 1 tsp lard. Once melted, reduce the heat to medium low and add 4 cloves grated garlic, 1 tbsp grated ginger root and 2 tbsp Japanese leek (naganegi). Mix occasionally to prevent burning and fry until fragrant.
Increase the heat to medium and add 150 g ground pork, fry until cooked through and slightly browning around the edges. Then add 1 tsp Japanese soy sauce (koikuchi shoyu), 1 tsp mirin, 1 tsp oyster sauce, ½ tsp sugar and ½ tsp chili bean sauce (toban djan). Stir fry until the pork is evenly coated and thoroughly browned.
Pour the bowl of broth from earlier into the wok and mix well, scraping the edges of the pan as you go. Bring to a boil then turn off the heat. Place 1 ½ tbsp yellow miso paste (awase) in a miso strainer, dip it in the broth and whisk thoroughly to incorporate it into the broth.
If you don't have a miso strainer, place the miso in a small heatproof bowl and add a splash of the broth. Whisk until loose and a smooth, paste-like consistency before pouring it into the wok.
Boil 2 portions ramen noodles for 30 seconds less than the time stated on the packaging.
Drain the noodles thoroughly and rinse with hot water to remove excess starch. Shake thoroughly, then divide them between serving bowls and pour the broth over the top.
Squeeze the spinach thoroughly and shake the beansprouts to remove any excess water. Arrange them on top of the noodles and spoon the seasoned pork mince in the center. Add your favorite toppings, I used canned sweet corn, finely chopped green onions, ramen eggs, roasted seaweed for sushi (nori) and a small pat of butter. Enjoy!
Notes
Use unsalted, unsweetened peanut butter: The broth rides on this jar, and salt or sugar hiding in it throws the seasoning off with no fix downstream.Whisk the broth in a bowl first: Loosen the peanut butter, sesame, and bouillon with a splash of hot water into a smooth paste before the rest of the water goes in. This pre-mix is what keeps the broth silky.Check your bouillon's strength: Every brand is concentrated differently. Mine builds soup at 1 tsp per 200 ml. Stronger brand, smaller spoonful.Dissolve the miso off the heat and taste: Cut the flame, whisk the miso in through a strainer or ladle, and let the last spoonful earn its place. Miso brands swing hard in salt.Pull the noodles 30 seconds early: A bowl of hot broth is a second stove and keeps cooking them. Drain hard, shake off the water, and serve right away.Squeeze the blanched greens dry: Spinach and bean sprouts hold more water than they look, and every hidden drop thins the broth you just balanced. Squeeze firmly, shake hard, then top the bowl.
