150 grams of sushi rice (about ¾ cup)
2.5 litres chicken stock
Soy sauce, for serving
Thinly sliced spring onions, green parts only, for serving
Finely chopped fresh ginger, for serving
Sesame oil, for serving
Rinse and drain the rice.
Put the rice in a pot with the chicken stock and bring to boil. Give the rice a good stir, scraping the bottom of the pan to prevent sticking, then lower the heat and half-cover the pan. Simmer gently for 1 1/2 to 2 hours, stirring every 15 minutes, until the grains have burst open and you have a thick congee.
Keep an eye on the pot to make sure the rice doesn't stick to the bottom. Towards the end of cooking, when the stock has become integrated with the rice and is the consistency of oatmeal, season lightly with salt to taste.
Serve the congee with a sprinkling of soy sauce, spring onion and ginger and a few drops of sesame oil to taste.
Tip: the congee will continue to thicken as it cools and can be thinned with additional chicken stock if desired.
