Fill a pot with a sufficient amount of water. Bring the water to a rolling boil over high heat, and cook the noodles until al dente. Once the noodles are cooked to your liking, drain them in a colander or sieve. Rinse them under cold running water to stop the cooking process and remove excess starch. This helps maintain the texture and prevents them from sticking together. Transfer the soba to a plate and serve immediately.
