A wholesome, deeply comforting soup crafted from slow-simmered stock, aromatic garden vegetables, and fresh herbs, served with crusty bread.
Bring the fish stock to a boil with lemongrass, galangal, and kaffir lime leaves.
Stir in the oyster mushrooms and simmer for 5 minutes.
Add the crab pieces and chilies; boil for 8 minutes until the shells turn bright red.
Remove from heat and stir in the fish sauce and lime juice.
Ladle into bowls, cracking the crab legs for easy eating, and garnish with coriander.
