This authentic Tom Saap recipe (Pork Rib Soup) delivers the perfect balance of spicy, sour, and savory flavors characteristic of northeastern Thai cuisine. The slow-simmered pork ribs become fall-off-the-bone tender while absorbing the aromatic essence of lemongrass, galangal, and kaffir lime leaves. Ready in under 2 hours with just 30 minutes of active preparation, this comforting soup offers a genuine taste of Thailand's countryside cooking traditions with every spoonful.
