-
Beat the crab meat, eggs, minced pork, 1 tbsp of the fish sauce and the pepper together. Set aside.
-
Fry the annatto seeds in the oil for 1 minute until it runs orange, then strain the seeds out.
-
Fry the shallots in the annatto oil for 4 minutes, then add the tomatoes and cook 5 minutes.
-
Pour in the stock, add the tamarind, sugar and remaining fish sauce and bring to a simmer.
-
Turn the heat down so the broth is barely moving.
-
Pour the crab mixture in slowly across the surface.
-
Leave it completely alone for 2 minutes, until it rises and sets into soft clouds.
-
Push the clouds gently to one side and add the tofu puffs. Simmer 3 minutes.
-
Soak or boil the vermicelli as the packet directs and divide between bowls.
-
Ladle the broth over, lift the crab clouds on top, and serve with herbs, beansprouts and lime.
