Penang laksa (Malay: Laksa Pulau Pinang), also known as asam laksa from the Malay for tamarind, comes from the Malaysian island of Penang. It is made with mackerel (ikan kembung) soup and its main distinguishing feature is the asam or tamarind which gives the soup a sour taste. The fish is poached and then flaked. Other ingredients that give Penang laksa its distinctive flavour include lemongrass, galangal (lengkuas) and chilli. Typical garnishes include mint, pineapple slices, thinly sliced onion, he-ko, a thick sweet prawn paste and use of torch ginger flower. This, and not 'curry mee' is the usual 'laksa' one gets in Penang. Perlis laksa (Malay: Laksa Perlis) and Kedah laksa (Malay: Laksa Kedah) is very similar to Penang laksa and only differs in the garnishing used. Sliced boiled eggs are usually added to the dish. In some places the soup is made of eel flesh. Ipoh laksa (Malay: Laksa Ipoh), from the Malaysian city of Ipoh, is similar to Penang laksa but has a more sour (rather than sweet) taste, and contains prawn paste.
