This is a sauce, or is it a salad? It's difficult to classify Thai dishes into English recipe classifications, so lets call it a salsa. It is normally served with rice, a shared dish is placed in the centre of the table and guests take a spoonful onto their plate to eat as they like. It is made from Thai winged beans, but long green beans can be used instead. The flavor is of coconut, both from coconut milk in the liquid and from desiccated coconut added to the salsa at the end. This is a dish suitable for 'gop-gam', a party dish served with alcoholic drinks.
