Cooking tips 💡
- Do not use soaked kelp directly, as it may develop a fishy smell in cold soup; always blanch it in boiling water for 10 seconds and rinse under cold water before using.
- Use clear, golden-hued tuna sauce rather than darker ones to keep the cold soup broth clear and clean.
- Maintain a ratio of about 1.5 tablespoons of tuna sauce per cup of water to ensure the seasoning remains balanced even as ice melts.
