- 2 Tbsp Mirin
- 2 Tbsp Soy sauce
- ½ tsp Salt

- Make the Noodle Soup: In a large pot, add water, dashi powder, mirin, soy sauce, and salt and boil over medium heat.
- Boil the soba noodles: While preparing the soup, add the soba noodles to a separate pot of boiling water and cook according to the package instructions. Stir the noodles with chopsticks to separate them while cooking.

Notes
- If your noodle soup is too salty, you can balance it by diluting it with water. Conversely, if it’s too mild, add more mentsuyu to enhance the flavor.
- Soba noodles typically take a couple of minutes to cook frozen noodles and around 10 minutes or more for dried or fresh noodles. The cooking time can vary depending on the type and brand of soba noodles, so please follow the package directions.
