Kake soba is the most simple form of Japanese soba noodles served with flavorful hot broth. This recipe includes how to make a delicious dashi base from scratch using bonito flakes (katsuobushi) and dried kelp (kombu).
Fill a saucepan with 3 cups water. Leave the konbu in the water for 30 minutes.
Bring the water (with konbu) to a boil. Once boiled, take the konbu out of the water, then turn down to medium heat.
Add the dried bonito to the konbu broth. Let simmer for 5 minutes. Pour the broth through a sieve and transfer to another bowl. Squeeze all the liquid out of the bonito to get maximum flavor. You should see about 2 ½ cup of dashi.
Put the dashi broth back into the saucepan. Add mirin and soy sauce. Cook over low heat for 2-3 minutes to cook off the alcohol.
Cook the soba 1 minute shorter than directed on the package. Drain the water and split the noodles into 2 bowls.
Pour the broth over the soba. Optional: top with scallions and shichimi pepper.
Notes
Dashi broth can be made in advance and kept refrigerated for up to 3 days.
