Bring the stock to a boil with lemongrass, galangal and torn lime leaves and simmer 5 minutes to infuse.
Add the mushrooms and crushed chilies and simmer 3 minutes.
Stir in the chili paste until dissolved and the broth turns fragrant and reddish.
Add the shrimp and cook 2 to 3 minutes until just pink and opaque.
Turn off the heat and season with fish sauce and lime juice, tasting for a hot, sour and savory balance.
Garnish with cilantro and serve immediately.
