In a 2 to 3 gallon stock pot, over medium-high heat, add the water, salt, bay leaves, carrots, celery, lemongrass and onion. Bring to a boil, then reduce the heat and simmer for 20 to 30 minutes. Once the vegetables have softened slightly, add the ginger, fruits, and tea. Allow the flavors to blend for 10 minutes, then add the bagged clams. Cook until the clams have opened about 10 to 14 minutes. Remove the clam bags from the water, and put them into a colander. Open the bags, drain and serve.
Serve with aioli topped baguettes or French bread.
