This light and healthy curry from Goa in Southern India is a delight. Coconut gives it sweetness, while tamarind adds a contrasting sourness. It's easy to make and really tasty.
Add the coconut milk, mix well, then add the tomato. If you are using whole tomatoes, you'll need to chop them finely first.
Cook for 5 minutes, then add the tamarind paste, sugar and chopped chillies. Let the flavours blend for a few minutes, then taste it and adjust the seasoning - you want a balance of sweet, sour and salty, so add more sugar , tamarind or salt if it is lacking.
Oil for sautéeing. If you can't get palm sugar, light brown will do. If you can't get tamarind, substitute white vinegar.
