Teochew fish porridge you buy at a hawker centre is fish soup with cooked rice added. The rice has very little flavour. This recipe cooks raw rice in dried shrimp stock. The rice is infused with lots of umami flavour before fish is added. Julienned dried squid and 冬菜 are mixed through at the end to increase the umami kick further.
Fish porridge is best eaten with a light soya sauce dip, with lime juice and thinly sliced bird's eye chillies added. The savoury, tangy dip brings out the sweetness of the fish.
