Nutrient-Dense Clam Miso Soup
This clam miso soup contain some of the most nutrient-dense ingredients: miso, sea vegetables, and shell fish.
Miso, made from fermented soybeans, is an excellent source of probiotics and vitamin K2. Note that we add miso into the soup near the end of the cooking process, so that we don’t kill off the probiotic microbes.
The kombu (kelp) and wakame (seaweed) contain minerals such as iodine, magnesium and calcium. Sea vegetables provide many nutrients that plants grown in soil are lacking.
Clams are amazing source of vitamin B12, omega-3, and iron.
Cooking Tips
- Kelp adds flavour into the dashi stock. Bring the kelp to a boil and then turn off the heat immediately. Don’t overcook the kelp, else it will turn mushy. Save boiled kelp for other dishes, such as stews or salads.
- You don’t need to boil the bonito flakes. Simply steep them in hot water for 10 minutes before straining.
- To rehydrate wakame, soak them in water for 15 minutes. Gently squeeze out excess water before use.
- To help miso dissolve easily into the soup, mix hot broth and miso paste into a thin sauce in a small bowl, then add the miso sauce into the soup pot. Do this near the end of the cooking process, so that the heat will not kill off the probiotic microbes.
