味噌汁（みそしる/Misoshiru） is a traditional Japanese soup. It is made with 出汁（だし/dashi – stock） with a small amount of 具（ぐ/gu – solid ingrediants） and flavoured with a paste called 味噌（みそ/miso）.
赤みそ（あかみそ/aka miso – red miso）,白みそ（しろみそ/shiro miso – white miso,八丁みそ（はっちょうみそ/hacchou miso）and合わせみそ（あわせみそ/awase miso – blended miso）.
They say miso soup has a lot of health benefits as it is a fermented food. Try one if you have never had it!
