Notes
Soak the chana overnight for easy pressure-cooking so that it cooks well.
Be sure to roast the coconut on medium to low flame to avoid burning it.
Cool the coconut before grinding it to a fine paste.
Adding tomatoes is optional and can be skipped.
If you prefer to grind the coconut without roasting, that's perfectly fine. However, roasting the coconut adds a deeper, more authentic flavor, and is highly recommended for the true taste of the dish.
