"This immensely popular snack was served in many bars in Malaysia and Singapore on a complimentary basis until ikan bilis (dried anchovies) became too expensive. Nowadays, it is still offered in upmarket cocktail bars as a menu item. It's easy to make; some cooks add a splash of sambal, others sprinkle crisp shallots, and others scatter just salt and pepper."
