Soba
Chilled soba is often served on a sieve-like bamboo tray called a zaru, sometimes garnished with bits of dried nori seaweed, with a dipping sauce known as soba tsuyu on the side. The tsuyu is made of a strong mixture of dashi, sweetened soy sauce and mirin. Using chopsticks, the diner picks up a small amount of soba from the tray and swirls it in the cold tsuyu before eating it.  Wasabi, scallions, and grated ginger are often mixed into the tsuyu.
