This variation, known as Tom Yum Goong Nam Khon, transforms the traditional clear broth into a rich and velvety soup with the addition of coconut milk and roasted chili paste. It retains the signature hot and sour punch of galangal and lemongrass but offers a smoother texture that perfectly balances the spicy heat.
Pour the chicken stock into a medium pot and bring it to a boil over high heat.
Add the lemongrass, galangal, and kaffir lime leaves. Reduce the heat to medium and simmer for 5 minutes to infuse the broth with the aromatics.
Stir in the Thai roasted chili paste (Nam Prik Pao) until fully dissolved, turning the broth a vibrant orange color.
Add the mushrooms and the fresh Thai chilies. Cook for 2-3 minutes until the mushrooms begin to soften.
Add the prawns to the pot. Cook for about 2 minutes, or just until they turn pink and opaque.
Lower the heat to a gentle simmer and stir in the coconut milk. Allow it to warm through for 1 minute, but do not let it boil vigorously to prevent curdling.
Remove the pot from the heat completely.
Stir in the fish sauce and fresh lime juice. Taste and adjust seasoning; it should be sour, salty, and spicy.
Ladle into bowls and garnish generously with fresh cilantro before serving.
