Recipe of Kombu Shiitake Stock - Food Recipes

A good start is to soak a 6" piece of kombu and a small handful of shiitake mushrooms in 3 qt of water overnight. Then simmer for as long as you can (I try to go for at least 4 hours). You can use this as is for a soup stock. Cut up whatever veggies you like and add them. If you like a bit more depth, add some miso.
