A vivid cobalt-blue pea flower native to tropical regions, which yields a blue dye when crushed in water. Used to colour sweets and cakes in Malaysia, Singapore and Thailand. Particularly spectacular are the blue tapioca and rice flour, pork-filled dumplings from Thailand called chor lada, sometimes shaped like flowers.
The Malay name is bunga biru, meaning ‘blue flower’.
