Miso, wakame, and roasted red peppers transform the salmon head stock into something divine. Add the flaked salmon, and the carrot and daikon waffles, which act like dumplings, and you have a salmon miso soup as nutritious as it is delicious.
The stock base is so important to this dish. Normally a miso soup is made using a dashi base, as with this Red Miso Soup or this salmon poached in miso dashi. This soup though uses a salmon head stock as the soup base. This style has more similarities to miso ramen dishes that traditional miso soup.
Unlike the red miso soup linked above, this salmon miso soup uses white miso. It has a milder and sweeter flavour, perfect complement to the salmon. Great article here on different types of miso.
Put some time into creating the salmon head stock. Store bought alternatives just won’t be the same. Make double the quantity and freeze half for next time. Update: added a post just on making salmon head stock.
The carrot daikon waffles added to the flavour and texture of this dish, acting a little like dumplings. However, the salmon miso soup itself is strong enough to stand on its own. Skip the waffles if you must, or serve with soba noodles.
