What is Sui-mono?
Suimono ("slurp dish") is a clear soup and one of two base soup types of Japanese cuisine – the other one is miso soup. Another name for suimono is sumashi-jiru (すまし汁). Suimono consists of the broth and three different soup ingredients. The broth usually is made with fresh dashi, soy sauce, and salt. Wandane (椀種) is the main ingredient that determines the flavor of the soup. This could be seafood, chicken, white-flesh fish or vegetarian foods like tofu or yuba. Seasonal vegetables or seaweed add some color. Suikuchi (吸い口) is another garnish, which, along with serving as a spice, defines the fragrance of the dish. For that purpose, yuzu peel, ginger, wasabi , or tree buds are used. Suimono are usually served in bowls with lids, so the aroma of the soup can develop in the air when they're opened. In a kaiseki menu, suimono are used as a starter.
