The dressing's thick, almost toffee-like body comes from hae ko, a black, treacly prawn paste that Penang is known for producing; it is a different product from the dried belacan block used in most Malaysian cooking.
Cucumber, pineapple, green mango, and jicama are tossed with fried tofu puffs, crisp fried dough fritters and cuttlefish in a dark, sticky dressing of hae ko (black prawn paste), tamarind, chilli, and sugar, then showered with crushed roasted peanuts. Hawkers chop the fruit to order at roadside carts and night markets across the island.
