You will need leftover cooked jasmine rice to make this recipe; if you don’t have any, steam the rice the day before or the morning you plan to make this recipe and refrigerate it until needed.
If you don’t have a microwave, pre-cook the diced potatoes by boiling or steaming until just-done and still firm, taking care not to let them over-cook.
Chinese dark soy gives this recipe lots of umami and deep flavour, but you can use light soy sauce if you prefer.
