How to Make It
In a large bowl, whisk the soy sauce with the sesame oil and vinegar.
Fill a medium bowl with ice water. In a steamer basket set in a large saucepan of simmering water, steam the asparagus until crisp-tender, 2 to 3 minutes. Transfer to the ice bath to cool. Drain and pat dry, then chop the asparagus into 2-inch lengths. Add the asparagus and daikon to the soy sauce dressing, season with salt and pepper and toss to coat. Transfer to plates, sprinkle with sesame seeds and togarashi and serve.
