What is Dasima (Kelp) ?
Dasima 다시마 is an edible dried kelp that is eaten and utilized throughout East Asia. In Korea, it is more commonly used to make broths and soups. Kelp gives the broth base a salty umami flavor without overpowering the dish. It is sold dried most often, but can also be found pickled in vinegar.
It is simmered in broth or water for a certain length of time before being removed and discarded. Once the kelp has been used in a stock, it can also be sliced and seasoned and eaten as a side dish if desired.
Dasima is so full of umami flavor and was the source of inspiration for MSG. It is also used extensively in Korean temple food as it can work as a great substitute for meat stock.
