Dashi broth: A traditional Japanese stock that adds a deep umami flavor to the soup.
Mushrooms: Adds an earthy flavor and texture to the soup.
Spinach: Fresh leaves that add a burst of color and nutrients.
Soy sauce: Provides a salty, umami flavor that enhances the overall taste.
Sesame oil: Adds a nutty aroma and richness to the soup.

Technique Tip for This Recipe
When preparing this Japanese salmon soup, ensure that the garlic and ginger are finely minced and grated, respectively, to maximize their flavor release. Sautéing them in sesame oil until fragrant creates a robust base for the dashi broth. Additionally, when adding the salmon fillets, avoid overcooking by keeping an eye on their texture; they should be opaque and flake easily with a fork. Finally, add the spinach at the end to preserve its vibrant color and nutritional value.

How to Store or Freeze This Soup
- Allow the Japanese salmon soup to cool to room temperature before storing. This prevents condensation and helps maintain the soup's texture and flavor.
- Transfer the soup into airtight containers. Use containers that are appropriately sized for the amount of soup you have to minimize air space, which can cause freezer burn.
- Label the containers with the date of preparation. This helps you keep track of how long the soup has been stored and ensures you consume it while it's still fresh.
- Store the soup in the refrigerator if you plan to consume it within 3-4 days. Make sure the temperature of your fridge is set to 40°F (4°C) or below.
- For longer storage, place the airtight containers in the freezer. The Japanese salmon soup can be frozen for up to 2-3 months without significant loss of quality.
- When ready to reheat, thaw the soup in the refrigerator overnight if frozen. This gradual thawing helps maintain the texture of the salmon and vegetables.
- Reheat the soup gently on the stovetop over medium heat. Stir occasionally to ensure even heating and to prevent the salmon from breaking apart.
- Avoid reheating the soup in the microwave, as this can cause uneven heating and may affect the texture of the salmon and spinach.
- If the soup appears too thick after reheating, add a splash of dashi broth or water to reach the desired consistency.
- Taste and adjust the seasoning with a bit more soy sauce if needed, as flavors can sometimes mellow during storage.
