how to make bonito & sea tangle soup stock
Soak the dried sea tangle in the water in a pan for 30 minutes.
Cook over medium heat for 4 to 5 minutes. Remove the sea tangle before the water begins to boil.
Add the bonito flakes. Reduce the heat, and simmer for 3 to 4 minutes.
Turn off the heat. Wait until all the bonito flakes sink to the bottom of the pan. Strain the liquid through a colander slowly to obtain the soup in a bowl.
