Relish raw banana, the south indian way A simple, dry subzi of raw bananas, tempered traditionally with mustard seeds, red chillies, et al, and garnished with grated coconut. While you can use any oil for this subzi, using coconut oil will add to the authenticity. Likewise, do not forget the curry leaves as more than half the flavour and aroma of the raw banana subzi comes from it. You can prepare yam also in a similar way.
