How To Make it?
At the soba noodle speciality shops in Japan, you can eat soba noodles that are freshly made and boiled, but it is difficult to have such luxury. Especially since the majority of my readers are living outside of Japan. Don’t despair, there is a way to bring out the delicious taste of fresh Soba noodles with dried noodles. The difference between freshly made and dried is the amount of moisture. So before you cook it, soak the dried noodles in water and let the noodles absorb the moisture. Read more about Soba noodles that I explained in detail in the soba noodles post here.
Tips & Tricks
- Soak the dried soba noodles in water for 15 minutes before cooking the noodles
- Use a large pot to cook with plenty of water
- Cook in shorter time because the dried noodles are already pre-soaked in water.
- Wash the cooked noodle immediately under running water to remove sliminess.
- Accompany with condiments that have fragrance and refreshing flavour
How to Serve Cold Soba Noodles?
If you have a bamboo strainer like in the photos, rinse the soba noodles under running water and drain the water and serve them on the bamboo strainer. Top with shredded nori seaweed and accompany mentsuyu and your choice of condiments. I usually eat cold soba noodles with grated ginger, chopped scallions, shiso leaves and myoga if I have. Oh, and tenkasu (the byproduct of tempura). Also you can serve soba noodles with Tempura, which is called Ten-zaru-soba.
A: Cold soba is eaten with dipping sauce in a small bowl, called soba-choko. I don’t drink the dipping sauce,. I throw it away once used, though leftover that has not been used can be used for different recipes such as making seasoned rice.
