Congee is like a rice porridge. It's very bland and has often been likened to wallpaper paste. You can really add any kind of toppings you like, as long as they're highly flavoured. Many people eat century eggs or salted duck eggs in congee. You can also have mixed meat congee; I have ghastly memories of eating congee with boiled pigs liver in it, which was similar in texture to licking velvet - very unpleasant.
1 mugful of white long grain rice (I use Thai)
6 mugfuls of water or stock
3 or 4 dried scallops (optional - they're very expensive)Bring the water to the boil in a large saucepan and add the rice. Simmer for an hour or so, stirring occasionally until thick. You may need to add more stock / water if it begins to catch.
Good toppings to use are salted peanuts, rinsed fermented black beans, chilli sauce (I used Nam Prik Pao), spring onions, soy sauce, white pepper and ginger. Marinated meats and seafood also work well, as do eggs.
It's not an earth shattering recipe, but rather good comfort food.
