The Indians and Thais have used banana flowers in their cooking for centuries. The large and heavy flower is packed with potassium, magnesium and iron and is large enough to provide a hearty and healthy dish for two to three people. See also this recipe for Banana Flower Soup.
Straight off the tree the banana flower is too bitter to eat. It must be prepared in advance. Discard the first 2 or 3 sepals – these beautiful dark maroon petals can be saved to serve your dish in later. Peeling back the dark sepals will reveal small elongated white or yellow flowers. These flowers develop into bananas. Save them to add as a garnish later, remember to soak them with the rest of the flower. Holding the tip of the flower first chop off the base of the stem – about and inch and a half is enough, discard this piece. Slice the flower through finely as you might chop a cabbage. Cut all of the flower this way. Put all of your flower, including the earlier saved pieces, into a pot and cover with clean salted water into which a lime or lemon has been squeezed. Set aside for at least an hour, then rinse thoroughly and towel dry or allow to drip dry.
