Bring two quarts of water to a rolling boil. Drop in meatballs. When they float, let them roll for 5 minutes. Add more water as needed.
Remove and reserve stock.
Strain into bais-marie containing fish sauce, salt, and preserved veggies.
Serve 3 meatballs in a small curry bowl on a bed of noodles, ½ cup of the reserved stock, pepper, scallions, cilantro and carrot.
