1.Wiping the surface of konbu removed some of its impurities (since white crystal attached to the
konbu is a delicious and tasty seasoning, don’t wipe too much.), put konbu into the pot and add
water soaked for 30 minutes or more. Put dried bonito flake into medicated bag.
2.Bring to a simmer over medium heat (about 10 to 15 minutes, there are many bubbles on edge of
konbu), remove konbu, and keep at a simmer (since konbu is not suitable for simmering, you
should remove konbu before boiling to avoid turbidity).
3.Add dried bonito flake medicated bag, heat and poach for 5 minutes, turn off, braise for 10
minutes to salvage (bonito flakes can not be long to cook, you should use a small fire to
let flavor release broth slowly), then skim froth clean.
