Most Korean soups need dried anchovies to make broth. If somebody doesn’t like strong anchovy flavor, like me, you can use this instead of real anchovies. It looks like a tea bag, but in the bag is dried anchovy powder. When you make broth with it, you can taste that it is milder than real anchovies. It is also convenient to use, because it is individually wrapped, and easy to remove from your broth after boiling.
