1. Tomatoes are added last so that it retain its shape and does not become overcooked.
2. Do not overcook ladies fingers or they will become too soft and mushy.
3. Fish meat can be substituted with fish head, fish tail or other types of seafood like prawns and squid.
4. When blending the spices, add some water into the blender or it will be difficult to blend.
5. Adjust the amount of water to your own preference. Use more water (but not too much or it will be too soupy) if you want a more watery curry and lesser water if you'd like a thicker curry. Personally, I like it somewhere in between.
5. Adjust the spices to suit your taste buds. If you prefer the dish to be spicier, use more dried chilies. And for a more sour taste, add more tamarind water into the curry.
