Brothy Noodle Bowl with Mushrooms and Chiles

Preparation

1. For the dashi:

   Step 1

   Bring mushrooms, ginger, chile, garlic, kombu, turmeric, and 4 1/2 cups water to a simmer in a medium saucepan over medium-high heat. Cover, reduce heat to very low, and gently simmer 25 minutes to allow aromatics to infuse and flavor the water. Strain dashi through a fine-mesh sieve into a large bowl; discard solids. Wipe out saucepan and pour dashi back in. Return to a simmer.

   Step 2

   Mix miso and 1 Tbsp. dashi in a small bowl, then stir into dashi in pan along with soy sauce; season with salt. Keep dashi hot if using right away.

   Step 3

   Do Ahead: Dashi can be made 2 days ahead. Let cool, then transfer to an airtight container and chill.

2. For the noodles and assembly:

   Step 4

   Heat olive oil in a medium skillet over medium-high. Cook mushrooms, stirring occasionally, until golden brown and beginning to crisp, about 5 minutes. Remove from heat, finely grate garlic over mushrooms, and mix well (garlic will cook in residual heat of mushrooms). Season with salt.

   Step 5

   Drop noodles into very hot dashi. Cover pan and let sit 3 minutes.

   Step 6

   Divide noodles and dashi among bowls. Top with mushrooms, radishes, herbs, fermented vegetables, and sesame seeds; drizzle with hot sauce and sesame oil.
