1. 1
   Pour a generous amount of chicken broth into a pot and add dried shiitake mushrooms, kombu, whole green onions, and smashed ginger to start infusing umami and aromatic flavor.
   ▶ ≈1:10
2. 2
   Simmer uncovered for about 30 minutes until the liquid reduces to roughly half its original volume, concentrating the broth and letting the kombu's natural gelatin thicken it slightly.
   ▶ ≈1:53
3. 3
   Strain the broth, removing the mushrooms, kombu, and aromatics, keeping only the liquid.
   ▶ ≈2:12
4. 4
   Season the broth with soy sauce, mirin, and miso. Taste the rehydrated shiitakes—if they still taste good, keep some in the mixture for texture.
   ▶ ≈2:18
5. 5
   Pour the seasoned concentrated broth into molds and freeze into cubes; each cube makes about two servings when reconstituted with water.
   ▶ ≈2:36
6. 6
   To serve, heat the cube with added water until melted, then combine with noodles (rice noodles or any noodle of choice) and your favorite toppings for instant ramen.
