Equipment
Ingredients
Instructions
- Prepare the toppings: Place the dried wakame in a small bowl and let it soak for about 5 minutes. Drain the seaweed completely. Finely chop the scallion.
- Make the soba soup: Put mentsuyu and water in a mediium saucepan and warm it up.
- Boil the soba noodles: While warming 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.
- Drain the noodles: Drain using a strainer and quickly rinse under running cold water to remove the extra starch.
- Serve: Serve the drained noodles in a bowl, pour the soup, and place the scallions and wakame on top.
Notes
- For the best results, cook the soba noodles separately from the soup. Cooking them together can make the broth cloudy and dilute the flavor.
- After cooking, briefly rinse the soba noodles with water to remove excess starch. This helps improve the texture and keeps the noodles from becoming sticky.
- If the soup tastes too salty, dilute it with a little water. If it tastes too mild, add more mentsuyu or a bit of salt until the flavor is just right.
