Also called banana flowers and banana blossoms, these are in fact the tender hearts of unopened banana flowers, which have been stripped of their purple petals. They are available fresh in some Asian markets and also canned or dried. Fresh banana buds discolour rapidly once they are sliced or shredded, so should be brushed with lemon juice to prevent this. Banana buds are used in northern Thailand to make a tasty, squash soup. They are also a popular salad ingredient, tasting rather like artichokes.
