Heat a pan on medium and add 1 tsp cooking oil. Add 100 g ground pork and season with a pinch of salt and pepper. Once browned, add 30 g Japanese leek (naganegi), ½ tbsp chili bean sauce (toban djan) and 1 tsp yellow miso paste (awase).
Stir fry until the ingredients are evenly distributed and the pork is cooked through, then remove from the heat and set aside for later.
Add the tare (sauce) ingredients to a saucepan and heat on low while stirring continuously. Once the sugar and chicken bouillon powder have completely dissolved, remove from the heat (no need to cook fully).
Pour 300 ml unsweetened soy milk into a measuring jug and pour in the tare mixture.
Mix well, cover and refrigerate until it's time to serve.
Bring a pot of water to a rolling boil and add 2 portions ramen noodles. Boil for 30 seconds to 1 minute longer than the instructions state. Prepare a bowl of ice-cold water with a mesh sieve placed on top. Drain the cooked ramen noodles and transfer straight to the ice water to cool.
Once nicely cold, drain the noodles and divide them between serving bowls. Pour the broth over the top and garnish with the seasoned ground pork, soft boiled eggs and your choice of summer vegetables.
