Instructions

  1. Step 1: In a large pot, combine 6 cups water, 1 piece dried kombu seaweed, 6 dried shiitake mushrooms, 1 sliced medium carrot, and 3 smashed garlic cloves. Let soak for 30 minutes, then bring to a gentle simmer over medium heat. Simmer uncovered for 40 minutes.

  4. Step 4: Cook 400 g fresh ramen noodles in boiling water for 2-3 minutes until tender, then drain.
  5. Step 5: Blanch 2 cups baby spinach in boiling water for 30 seconds, then drain.
  6. Step 6: Divide noodles into 4 bowls. Ladle hot broth with mushrooms over noodles. Top each bowl with 1/2 cup blanched spinach, 1/4 cup sliced green onions, a sheet of nori, and a sprinkle of 1 tbsp toasted sesame seeds.
