Tom Kha is mildy Thai soup,taste creammy,sweetness from coconut milk,famous one is with chicken,but i cook with fish today as my own favorite ,first of all heat coconut milk in soup pot,add sliced lemongrass,kaffir lime leaves,galangal ,mushroom,shallots,fresh chili ,all are sliced ! ..keep them boil on medium heat about 3 mins

Add sliced fish into soup,but dont stir ,wait to another 2 mins,add tomato,fishsauce,both sugars,lime juice,stir only to mix,cook it 3 more mins,add coriander,spring onion,heat off
