The most important trick is not to let the curry boil or simmer or else yogurt will curdle.
Ground coconut definitely enhances the taste and gives the curry a little thicker consistency.
The tempering on the top makes it more appealing especially when you have guests over.
This curry is supposed to be a little sour. If using low fat or other yogurt dilute as necessary, the liquid shouldn't be too watery or thick.
Ideal to be served with rice.
