Notes
- When boiling somen, use plenty of water. This gives the noodles enough room to move freely and prevents them from sticking together.
- After boiling, rinse the noodles immediately under cold running water to stop the cooking process and remove excess starch. This helps achieve a firm and chewy texture.
- Somen noodles tend to stick together over time. Toss them gently with a little cold water or add ice cubes to the serving bowl to prevent this.
