Peel off the outermost several layers of the banana blossom until the small arrays of flowers are less developed and the large leaves are a white yellow instead of deep purple.
Cut the remaining banana blossom into quarters and slice thinly. Immediately place the cut pieces in a bowl of water.
The small flowers can be discarded or used in the curry. To use the flowers, peel out the small, hard pistil. It is hard and can be unpleasant to eat.
Chop the flowers as well and add to the bowl of water.
Curry
Heat the oil on medium to high heat and fry the curry leaves for a few seconds (if using).
Add the onion, garlic and green chili. Fry until onion is golden.
Meanwhile, drain and rinse the chopped banana blossom. Squeeze out the water.
Add spices and ginger and stir in the banana blossom.
Cook for 5 minutes.
Add the coconut milk and cook for another 5 minutes.
