Tips
1. Clean abalone shell and simmer the shells with abalone together, which also make the soup taste good.
2. Wash angelica, sealwort, and fleece-flower before putting in the soup bag. These dietary therapy ingredients have sand and mud when produce, make sure they are clean before adding to the soup.
3. Use dried abalone if you like. It will have more seafood flavor, but make sure soak dried abalone in advanced.
