AT A GLANCE
Noodles are great served cold. The trick is to refresh them under cold running water to rinse off the extra starch and stop them cooking. If you aren't using them immediately, toss them in oil and refrigerate them. Any fish works well here, as does silken tofu.
|01||For tamari-dashi dressing, place bonito flakes in a bowl, cover with 100ml boiling water and stir gently for 2 minutes to infuse. Strain, then whisk in remaining ingredients.|
|02||Dry-roast sesame seeds in a frying pan over medium-high heat, stirring constantly, until golden (3-5 minutes). Transfer to a plate to cool.|
|03||Cook soba in a large saucepan of boiling salted water, arresting the boiling once or twice during cooking by adding ½ cup cold water, until soba are tender (3-4 minutes). Drain, then gently rinse under cold water. Drain again and transfer to a bowl. Toss with grapeseed oil to coat, then refrigerate until chilled (1 hour).|
|04||Roll bonito in toasted sesame seeds to coat, then thinly slice with a good sharp knife. Divide noodles among bowls, top with fish, pickled ginger, edamame, shiso leaves and spring onion, drizzle with dressing and serve.|
