Dashi Broth Soup Stock and Soba Sauce Soup Recipe

What is Dashi Broth Soup Stock?

Dashi broth soup stock is a traditional Japanese base made from natural ingredients like kombu (kelp) and bonito flakes (katsuobushi). It’s light, clear, and full of savory umami flavor, which enhances every dish it touches. Unlike Western-style stocks that require long simmering, dashi is quick and easy to prepare, taking only a few minutes. It’s commonly used in soups, sauces, and dipping broths such as soba sauce soup.

There are different types of dashi, but the most common is made from kombu and bonito flakes. Kombu provides a subtle sea flavor, while bonito flakes add a smoky, fishy richness that perfectly complements noodle dishes.

Ingredients for Dashi Broth Soup Stock:

• 4 cups water
• 1 piece kombu (about 4×4 inches)
• 1 cup bonito flakes
• Optional: 1 dried shiitake mushroom for extra umami

How to Make Dashi Broth Soup Stock:

1. Prepare the kombu: Wipe the kombu gently with a damp cloth to clean it. Avoid scrubbing off the white powdery surface, as it holds much of the umami flavor.
2. Heat the water: Add the kombu to a pot with 4 cups of water. Slowly heat over medium flame until just before boiling. Remove the kombu when bubbles begin to appear.
3. Add bonito flakes: Add the bonito flakes to the pot and let them steep for about two minutes.
4. Strain the broth: Turn off the heat, let the flakes settle, then strain the liquid using a fine sieve or cheesecloth. The result is a clear, flavorful dashi broth soup stock ready to use.

Making Soba Sauce Soup:

Soba noodles are a staple of Japanese cuisine, often enjoyed with a light and flavorful broth. Using freshly prepared dashi broth soup stock as the base, you can create a perfect soba sauce soup for a comforting meal.

Ingredients for Soba Sauce Soup:

• 2 cups dashi broth soup stock
• 3 tablespoons soy sauce
• 2 tablespoons mirin (sweet rice wine)
• 1 teaspoon sugar (optional)
• Cooked soba noodles
• Green onions and nori strips for garnish

Instructions:

1. In a small saucepan, combine the dashi broth, soy sauce, mirin, and sugar.
2. Bring the mixture to a gentle simmer for two to three minutes, allowing the flavors to blend.
3. Adjust seasoning as per your taste.
4. Pour the hot broth over cooked soba noodles or serve as a dipping sauce for cold noodles.
5. Garnish with chopped green onions and nori for a traditional touch.

Serving Tips and Variations:

• For a richer taste, add a soft-boiled egg or tofu cubes to your soba sauce soup.
• To make a cold version, refrigerate the broth and serve it as a dipping sauce with chilled soba noodles.
• You can store leftover dashi broth in the refrigerator for up to three days or freeze it for later use.
